Thanks @RazcoDev for the early work here, and @asafc for the review. Invite approval has since shipped in the SDK through #117, #118, #119 and #120, as a dedicated user_invites API rather than a method on users. It's available on both the async and sync clients:

from permit.api.models import ElementsUserInviteApprove

user = await permit.api.user_invites.approve(
    user_invite_id=invite.id,
    approve_data=ElementsUserInviteApprove(email="alice@example.com", key="alice", attributes={}),
)

It calls the same /v2/facts/{project}/{environment}/user_invites/{user_invite_id}/approve endpoint this PR targets, and returns a UserRead. attributes is currently required by the model, so pass {} when you don't need any.

The branch also conflicts with main now: the required_permissions / required_context decorators it uses were removed in a later refactor. So I'm closing this in favor of the shipped API. Thanks again!
