How to use with ECA module

I have implemented an ECA plugin over in Social Post Mastodon: https://git.drupalcode.org/project/social_post_mastodon/-/blob/3.0.x/src...

I would try doing it here, but I haven't had any success with twitter in years now. I haven't even been able to log in because verification codes never get sent and twitter support never responds to support requests. So for anyone that has twitter working, I hope the example in mastodon helps with getting this set up over here. If I do end up getting into Twitter, then maybe I will come back to this.

I went ahead and made an issue fork, but haven't tested it yet, bc like I said I haven't been able to log into twitter. But I think it is set up correctly. I personally like the ability to choose which user should post from a token, as it provides the flexibility to get the user id from a field or from current user, or wherever. Same rules as usual apply when using tokens. My typical values for the configuration fields would look something like:

[current-user:id]
[node:field_facebook_post:value]

Even though I may not be able to use this, I would love feedback on this as it relates to the work I am doing on facebook and mastodon social post modules.
