Setup online_users view permissions
Head over to the Permissions tab under online_users
view to add relevant permissions.
Select permission
Here in this view, we only want the user to be able to select data and not do any mutations. Hence we don't define any permission for insert, update or delete.
For Row select permission, choose Without any checks
and under Column select permission, choose both the columns id
and last_seen
.
Click on Save Permissions
. You have completed all access control rules required for the realtime todo app.
