Hi Arrotu - I'm working on mini app cataloging from the Neynar side. "Step 1" from your guide won't be necessary soon. I'm working on a fix!
"Step 2" I don't think this is best practice. I would like to help address the issues you were seeing with the standard fc:frame metadata tag. That is the correct way to embed miniapps
Steps 3 and 4 I think are good practice for everyone.
