How to update the flow?

I am in the need to update a flow I published in the "flows" section. I updated the flow in github, but it is not updated on NR section. Do I have to remove and recreate the post?

If you login via the github icon in the top right corner, you should then see a 'refresh from github' action in the sidebar:

Yes, I did it
But it refreshed the text, not the flow.
The flow is added in github as an attachment file
