I think this will be solved by this #16623 which will make the new flow default (and the new flow doesn't have Edit permission screen anymore).

assigning to @VSaric as it looks like their PR fixes this issue
#16740

[bschorchit]

We cannot merge #16740 for 10.24 though :/

The new token allowance flow has yet to be released under Settings > Experimental before we can make it the default flow on a later release. The target is to merge it for 10.25 if all goes well while this feature is under experimental.
