[MM3-users] integrate subscribe form in Website -> CSRF-token

Hello, we wanted to integrate a subscribe-form in our website after Update from Mailman2 to Mailman3. Before it was quiet easy and supposedly still is, but we can't figure out what to do with the CSRF-token-problem.

Is there anywhere a documentation on this? We can't find one.

If not, I would like to post more on what we tried with the html-code and what is coming up afterwards.

(forbidden 403 - CSRF-verification failed. Request aborted.)

Thanks in advance! Jens.
