Functionality to lookup the "Created By" or "Modified By" user's membership of the Sharepoint site groups.
This would allow a simple rejection in a flow (for example promote an item) if the user was trying to promote their own item.
A user needs create and edit access to their own item, but if a drop down is used to trigger a list update flow to promote an item (e.g. email or send to a webhook) then it would be nice to be able to reject the change based on the users permissions.
I am not aware of another way to accompish this.
Outline of process, to prevent user submitting to "Promoted" status when not a member of approvers SharePoint group:
User creates an item, default "New" status -> flow sends to webhook for discussion in Teams
Manger / approver decides the item is valid and changes status to "Promoted"" -> the same flow needs to check the approver is a member of the approvers group, then send to another Team (managers) for discussion
