 Yes, on chain address is fine, it's the bolt12 offer I'm asking about specifically.  
 I believe Core Lightning has bolt12 support, while I think LND does not. The backend of your Start9 should have both options but I've never tried core or BOLT12 personally.  
 I believe there's options out there. Going to have to piece this together. 

Basically it's a way of signing via onchain to point at a LN wallet.
