Ideas on dealing with path attribute in Set-Cookie header.

[Prog-Jacob]

Beginner here👋

I am developing a gRPC API with the browser being the client. I am using access and refresh tokens authentication model. What I am familiar with in a REST API is that I would set a cookie with the "path" attribute to a dedicated endpoint "/refresh-token" or something. However, I have no idea how to do such thing using gRPC. One way is not to specify a path attribute, but I find it inconvenient to send unnecessary cookies with every request. Any ideas?

Thanks in advance!
