Short answer
Medicare pays first for drugs, so a GLP-1 runs through your Medicare drug plan.
Medicare.gov says people with both Medicare and full Medicaid are dual-eligible, that Medicare pays first, and that they are automatically enrolled in a Medicare drug plan that covers their drugs. So a GLP-1 for a covered indication runs through that Part D plan. One nuance matters: CMS says the GLP-1 Bridge provides no low-income subsidy, so the flat $50 Bridge copay applies even to dual-eligibles who normally get Extra Help.
