Lichess. How close the connection?

[9acca9]

Hi.
This is a question, not about certabo-lichess. Maybe you can help me. Im using berserk to manage the lichess api.
I want to cancel a seek i create. How i can do that? In the lichess api reference says this:

Keep the connection open to keep the seek active.

If the client closes the connection, the seek is canceled. This way, if the client terminates, the user won't be paired in a game they wouldn't play. When the seek is accepted, or expires, the server closes the connection.

But, how close the connection? Dont find anything, probably is too obvius and im ignorant. im using berserk.

Thanks!
