Tubeless setup help needed

Hey guys, I’m posting here as i am quite desperate with this setup.

Not my first tubeless wheels but somehow I cannot make this one work.

As a recap:
Wheels are brand new, Hunt 4season.
Tires have around 500km (used with tubes)
The tires are seated correctly using a compressor.
Muc-off sealant was added (100ml per wheel as recommended on the bottle for 700c)
Both wheels were shaken, spinned, cursed at for 5min each, as the protocol requests.
There were both left on the side, flat, overnight on a bucket.

This morning I try again to inflate both but see soap bubbles on the side I left them on overnight.

Am i missing something?
Do I need to add more sealant?
Should I forget about the tubeless concept and go with inner tubes?

Thanks
