Never heard of this repo or library, but in the readme:

"Yet another remote desktop software, written in Rust. Works out of the box, no configuration required. You have full control of your data, with no concerns about security"....

Yikes. Please don't believe in every repo face value. Your best bet is to generate your own certs (https://github.com/FiloSottile/mkcert) and sign the dlls yourself.
