Inclusion Criteria: * Male or female. * Age 18-75 years (both inclusive) at the time of signing the informed consent. * Diagnosed with type 2 diabetes more than or equal to (≥)180 days before screening. * Only stable daily dose(s) of metformin at effective or maximum tolerated dose, as judged by the investigator for at least 90 days before screening. If additional oral antidiabetic drug (OAD) is required, only stable dose(s) of sodium-glucose cotransporter-2 inhibitors (SGLT2i) is permitted, and this must also have been maintained for at least 90 days before screening. * HbA1c at screening of 6.5-9.5% \[48-80 millimole per mole (mmol/mol)\] (both inclusive) if on metformin only, or 6.0-9.0% (42-75 mmol/mol) (both inclusive) if on metformin in combination with SGLT2i. Exclusion Criteria: * Female who is pregnant, breast-feeding or intends to become pregnant or is of childbearing potential and not using highly effective contraceptive method. * Presence of type 1 diabetes. * Any clinically significant body weight change (≥5% self-reported change) or dieting attempts (e.g., participation in a weight reduction program) within 90 days before screening. * Treatment with any medication for the indication of T2D or weight management 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. * Treatment with a GLP-1 receptor agonist. * Participant with diabetic retinopathy or maculopathy who received treatment with retinal photocoagulation, vitrectomy or anti-Vascular Endothelial Growth Factor (anti-VEGF) before screening or are expected to require treatment after screening. Diabetic retinopathy or maculopathy must be verified by an eye examination performed within 90 days before screening or in the period between screening and randomisation. Pharmacological pupil-dilation is a requirement unless using a digital fundus photography camera specified for non-dilated examination. * Presence or history of cardiovascular disease including stable and unstable angina pectoris, myocardial infarction, transient ischaemic attack, stroke, cardiac decompensation, clinically significant arrhythmias or clinically significant conduction disorders within 180 days before screening. * Renal impairment with estimated glomerular filtration rate (eGFR) less than (\<) 60.0 milliliter per minute per meter square (ml/min/1.73 m\^2) at screening.
