Special thanks to @abbodi1406 & @Enthousiast for pointing out the way to create 22621 iso with only the apps I need. Bless you guys and the creators of UUPDump.
22621 rp is appeared only in uup (but not windows update). idk why? but it may uploaded to test is 22H2 can be possible to send builds to release preview
