file Learning UML: Sequence Diagrams

Hello! I'm not sure if I'm supposed to post here so please move this if I'm posting in the wrong location :cheer:

I'm learning UML and I'm really confused about sequence diagrams!

I was wondering if somebody could take a quick look at this sequence diagram and let me know if it makes sense?

Essentially, I'm trying to show how an (extremely simple) software can help a bank with loan proposals.

The credit employee can refuse or accept the loan proposal demand. If he/she accepts, then the branch manager will obtain the proposal and discuss with the client in person. Once the client has his/her answer, the branch manager will enter in the response of refuse, accept or accept with modifications. Would the attached diagram make sense? Or do I need another class in between Loan Proposal and Branch Manager?

Thanks in advance!
