How to access custom sessions

[dbain85]

If you create a custom session as suggested in the docs, what's the best practice for accessing this? Ideally I need to access custom session values in the server.WithToolFilter, I see I can use server.ClientSessionFromContext(ctx) but this only returns the default session.

Overall I'm looking to filter tools based on the user's scopes obtained from their bearer token, so open to suggestions if there's an efficient way to achieve this.

I'm using NewStreamableHTTPServer.
