Chat API

I've been trying to access and send chat messages through the reddit API, with no success.

This thread mentions three potential ways to do this other than PRAW (reddit's endpoint/Sendbird API/some Git repo) but none of these work: The Git repo uses sb_access_token that is supposed to be returned by the /api/v1/sendbird/me endpoint, but isn't. This endpoint isn't present on the API documentation either, and Sendbird seems to only allow API access to your own applications.

I haven't seen any communication on this from the Reddit devs either, but since the linked post is >1 year old I am assuming they removed it.

Is there some way to deal with chats or did they completely lock it down ? Does anyone have experience with a Selenium-based solution that works ?
