Approve Access is a permission on LENS that allows a user to approve or reject access requests from other users. Having this toggle on will cause LENS to send emails each time a user requests access to the board. These requests can be managed through email or through the User Management page.
To stop receiving these Approve Access emails, simply toggle off the permission.
Navigate to the User Management page
Find your own user account and click on your name
toggle off "Approve Access" on the board you'd no longer like to approve
Don't hesitate to reach out to us at LENS Support if you have any questions!
