Once this is configured:
oauth_expire: 3600
oauth_access:
- allow:
- user:
- "admin#localhost" # add your user name
Try first with the command line:
❯ ejabberdctl oauth_issue_token admin#localhost 3600 "registered_users;muc_online_rooms"
yamdcY4TGqltWCprCnunZjrz7ZNSmL8d [<<"registered_users">>,<<"muc_online_rooms">>] 3600 seconds
Once that works, you can try to obtain the token using the web, which requires more configuration steps.
