How do I assign Delegated Administration via DML or query it via SOQL?

Question

I would like to assign power-users to be admins of Delegated Administration groups a bit easier than the click-through manual process.

Is there a way I can query admins via SOQL or assign admins via DML?

I can do these assignments for other setup-type operations (PermissionSetAssignment, Profile, UserTerritory2Association, UserRole, GroupMember). Is there a way to do it for Delegated Administration Groups? If so, how?

If not, is there any other programmatic API for user assignments to delegate admin groups?

Answer 1

you cannot add/delete delegated admin programmatically.

it mean delegated admin is metadata(not sobject data). but salesforce does not support it (yet).
