Ideally this can be a part of the UserClient.

I wrote a similar logout method for this project when I forked this project a while ago. I can throw together something that should get logout functionality available from the SDK.

@irby Could you please provide the code that does that? I would like to add it manually to my code until you make a PR (or I could make a PR too if you want). Thanks!

@IgnisDa I'm about 85% done with the PR, and should have it posted here in the next day or so. But, here's the code I wrote some months ago that will expose an endpoint to log out the user.

Updating the Session Manager to have a DeleteCookie method: https://github.com/irby/passwordless-authenticator-poc/blob/main/authenticator-backend/session/session.go#L182 (Note updating the Manager interface on line 19)

Adding the DeleteCookie method within the Webauthn Test: https://github.com/irby/passwordless-authenticator-poc/blob/main/authenticator-backend/handler/webauthn_test.go#L203

Adding a logout method on user handler: https://github.com/irby/passwordless-authenticator-poc/blob/main/authenticator-backend/handler/user.go#L545

Logout endpoint exposed on the public server: https://github.com/irby/passwordless-authenticator-poc/blob/main/authenticator-backend/server/public_router.go#L69

Once this is added, you should be able to call the logout with POST /users/logout.

While making my PR, I noted some opportunities to improve my code. So, my PR will have some different code than what is in here. Just FYI 😅
