Welcome to the Atlassian developer community @FrankKe,
I think the short answer is, “Not yet.”
We’re close. Atlassian has been working on a set of changes under the umbrella of RFC-8 Forge Remote. And several of the milestones mentioned in that RFC are now available in early access. However, it sounds like what you need is milestone 3, which is not yet available. We adjusted based on feedback and changed the order of the milestones; hence, milestone 4 came before 3. I don’t have any predictions on when milestone 3 might be available.
