Workflow Condition from Froge app can only be edited by Jira admin

Hello,

I have a Jira Forge app hat adds a Jira workflow condition.

In my test project every user has the Edit Workflows permission. If I now try to add my Condition to a transition I get an error. At first my UI starts to load, and then I get an error, because
https://<my-site>.atlassian.net/rest/internal/2/forge/context/token
returns 400 with
{"errorMessages":["The user must be a Jira admin to call this extension"],"errors":{}}.
If a Jira admin tries to add the condition, it works.

I could not find any documentation that states, that only Jira admins can add or edit Condition introduced by my Forge app. Is this really the case or am I missing some scopes or other configurations?

Best,
Tim
