Allow access tokens to push despite branch permissions

[Martin Karing]

How can I enable an access token to push to a branch that is protected from direct pushes from normal users.

I can't seem to setup the required permissions in Bitbucket.

I tried to setup a service account to work around that in admin.atlassian.com, but such a service user can't login to bitbucket, but it can get the required permissions to push despite the branch protections.

Who do I get this working?
