The main user is kishan.storetransform.com, who created a page titled "WordPress Service" and a group named "Test FB Group."
Both kishan.storetransform.com and the "WordPress Service" page have admin access to the "Test FB Group," and both can post in the group.
However, I can only access the posts made by kishan.storetransform.com, not those made by the "WordPress Service" page.
