Call connections.check_ad_account_access

Confirm we actually have access to a brand's shared ad account — 'check if the ad account access came through', 'did they finish sharing the ad account'. Ask the platform what access we ACTUALLY have on this brand's ad account right now, and record the answer. Call it when the operator says they have finished sharing the account, or asks whether it came through. It needs their ad account id already on file — connections.ad_account_status shows whether we have one. On TikTok this is what catches the common failure: TikTok's default sharing level is view-only, so a shared account often arrives with access that cannot run campaigns, and this check surfaces the step that fixes it. It only LOOKS: nothing is changed on their ad account, nothing is spent, and the only thing written is our own record of what came back — so it is always safe to run again. Not for asking the platform for access — that is connections.request_ad_account_access.

Every result names the workspace it ran in. Say which workspace the answer is about. When the account has more than one workspace and none is selected, this tool refuses with workspace_ambiguous and lists the choices — offer them, never pick one.
