How to verify a message from Hub on client side?

I see the `dataBytes` generated from the protobufs [pic1] but it always returns nothing [pic2].

Should I JSON stringify the message data? It can contain bigints so that wouldn't be serializable.

What then?

Tbh didn’t figure it out. Too much code, can you pinpoint to exactly where verification happens?

It all would make sense if dataBytes weren’t null - I wonder how I need to transform the data to correctly verify it.

@horsefacts.eth maybe you can help with this?
