Groups claim not showing in Token Preview

I have added a “groups” claim to my custom authorization server but my app is not receiving it and it’s not showing in the Token Preview.

I’m not using the default authorization server. I have added one.
Please advise.

the claim will not be included if it is empty; in this case do you have any okta groups that starts with *?

If you want to return all okta groups you will have to use Matches regex: .*

below is the guide on setting up a groups claim with all the available options
