No comment from bot on stale issues

[0x90d]

First of all please bear with me I'm a beginner when it comes to github (actions).

What I want:
Pretty much everything which its doing by default, EXCEPT that the bot put any issue into stale by itself. I want to manually add a stale label myself to an issue. Then a bot should immediately place a comment, that the issue is marked for stale etc. And the bot should close the issue after 7 days. If someone replies the bot should automatically remove the stale label. The desired behavior is (almost?) identical to https://github.com/dotnet/runtime repo.

What I did:
I created a workflow file: https://github.com/0x90d/videoduplicatefinder/blob/master/.github/workflows/stale.yml
I've created a label stale and added it to an issue: 0x90d/videoduplicatefinder#477

My problem:
When added the label nothing happend. (I know this makes sense because my workflow is set to run every 30 minutes. But I dont know how to change it to react on labeled an issue AND to run every 30 minutes which I expect is necessary to auto close stale issues). But even after its first run it did not add the comment to the issue I've marked as stale.

My assumption is that the bot is able to do what I want and I'm just making mistakes here in which I was using the discussion in first place. Can anyone please tell me what I'm doing wrong?
