How can you reply to a Tweet on Twitter (by it's ID)?

Thanks. I had a look at the docs and it appears you can post with ID using Twitters V2 API on the free tier.

I can’t get the connection (to the V2 API) to work using the HTTP module to test it though.

It appears that it can be done but I can’t work it out [Connecting to Twitter with OAuth 2.0 and PKCE]
