By default, the site being visited grants same-origin permission, but cross-origin permission needs explicit allowance via a permissions policy. Interest group owners can implicitly grant permission by calling the function from a same-origin iframe. Alternatively, they can delegate permission to other domains through a `.well-known` URL, which defines permissions for joining and leaving interest groups for various origins. The function also uses cors mode for the fetched response.\n"]]
