About "Community Member Page Layout"

The page layout created in the "Community Member Page Layout" of the User object is the layout used when adding community members in Experience Cloud sites. 
This page layout can be confirmed in the following operations:

• The popup screen displayed when clicking the "Add Member" button in the Community Members related list.
• The popup screen displayed when navigating to the account management page from the profile menu "My Account" and clicking the "Add Member" button.

※ Internal users cannot see the profile menu "My Account".
※ Community users can see the "Add Member" button if the "Delegated External User Administrator" permission is enabled in their profile.
※ Once created, the "Community Member Page Layout" cannot be deleted.

If no page layout is set in the "Community Member Page Layout", the popup screen of the page layout from the "User Page Layout" of the User object will be displayed.
