create oauth2 client id and client secret

Hi, I want to enable people to login on my website with their lichess account via oauth2.
I ́ve implemented this with other providers.
But on Lichess I cannot find where to create clientid and client secret an where to define a callback URL like it is possible with other providers (Google etc.)
Who can help?

oauth login with lichess is implemented in many places, e.g.

lichess4545.com / https://github.com/Lichess4545/heltour
pychess.org / https://github.com/gbtami/pychess-variants
openingtree.com / https://github.com/openingtree/openingtree

you could check how they did it.

You don't need to register "an app" like you have to do with other services.
