Inclusion Criteria: * Informed consent obtained before any study-related activities. Study-related activities are any procedures that are carried out as part of the study, including activities to determine suitability for the study. * Japanese male or female. * Age 18 years or above at the time of signing the informed consent. * Diagnosed with type 2 diabetes (T2D) greater than or equal to (≥) 90 days prior to day of screening. * Glycated haemoglobin (HbA1c) of 7.0-10.5 percent (%) (53-91 millimoles per mole \[mmol /mol\]) (both inclusive) at screening. * Stable daily dose(s) ≥ 60 days before screening with any 1-2 of the following oral antidiabetic drugs (OADs): Sulfonylurea (SU), glinide, thiazolidinedione (TZD), alpha-glucosidase inhibitor (α-GI), sodium-glucose cotransporter 2 (SGLT-2) inhibitor or metformin (effective or maximum tolerated dose as judged by the investigator) according to Japanese labelling. Exclusion Criteria: * Known or suspected hypersensitivity to study intervention(s) or related products. * Previous participation in this study. Participation is defined as signed informed consent. * Female who is pregnant, breast-feeding or intends to become pregnant or is of childbearing potential and not using adequate contraceptive method. * Current participation (i.e., signed informed consent) in any other interventional clinical study. * Exposure to an investigational medicinal product within 90 days or 5 half-lives of the investigational medicinal product (if known), whichever is longer, before screening. * Any disorder, unwillingness or inability which in the investigator's opinion, might jeopardise the participant's safety or compliance with the protocol. * Previous or planned (during the study period) obesity treatment with surgery or a weight loss device. * Anticipated initiation or change in concomitant medications for more than 14 consecutive days affecting weight or glucose metabolism. * Use of any medication with unknown or unspecified content within 90 days before screening. * Personal or first degree relative(s) history of multiple endocrine neoplasia type 2 or medullary thyroid carcinoma. * Presence of clinically significant gastrointestinal disorders potentially affecting absorption of drugs and/or nutrients, as judged by the investigator. * History or presence of pancreatitis (acute or chronic). * History of major surgical procedures involving the stomach potentially affecting absorption of study products or current presence of gastrointestinal implant. * Myocardial infarction, stroke, transient ischaemic attack or hospitalization for unstable angina pectoris within 60 days before screening. * Chronic heart failure classified as being in New York Heart Association (NYHA) Class IV at screening. * Planned coronary, carotid or peripheral artery revascularisation. * Uncontrolled and potentially unstable diabetic retinopathy or maculopathy. Verified within 90 days before screening or in the period between screening and randomisation. * Impaired liver function, defined as Alanine Aminotransferase (ALT) ≥ 2.5 times or Bilirubin \>1.5 times upper normal limit at screening. * Renal impairment with estimated glomerular filtration rate (eGFR) less than (\<) 30 millilitres per minute per meter square (mL/min/1.73 m\^2) as per 2021 Chronic Kidney Disease Epidemiology Collaboration formula (CKD-EPI) formula (by creatinine) at screening. * Treatment with medication for diabetes or obesity other than stated in the inclusion criteria within 90 days before screening. However, short term insulin treatment for a maximum of 14 consecutive days and prior insulin treatment for gestational diabetes are allowed. * Presence or history of malignant neoplasms or in situ carcinomas within 5 years before screening. * Any episodes of diabetic ketoacidosis within 90 days before screening.
