Documentation outdated

Hi, thank you for this action.

In the documentation "Sending messages requires generating of an access token, which can be done with curl, and is detailed here.", the link to the details is going to https://matrix.org/docs/guides/client-server-api where a warning is stated "This guide is badly outdated and should not be used anymore! It is only kept for posterity.". So I am lost. Thanks for helping.
