Failed-Delete Message: Initiator (8:orgid:**) is not allowed to delete message

I am trying to delete a message inside Teams Channel using Graph API, the chat was generated using copilot agent. now i used this action to do the delete:-

and this endpoint:-

POST /teams/{teamsId}/channels/{channelId}/messages/{chatMessageId}/softDelete

but we got this error message:-

AclCheckFailed-Delete Message: Initiator (8:orgid:68******3ca) is not allowed to delete message

Although the user who run the flow is teams owner + we have this setting enabled to allow owners to delete message:-

any advice?

Thanks
