Hey @neoromantic,

I will take a quick look now, I am still working through the backlog of PRs. We do consider all PRs but sometimes we don't have a chance to reply to them all.

Hey @neoromantic,

I have taken a look at your change, what that function does and what options the node has available and this change doesn't actually add anything to the sendChatAction API call.

Send Chat Action has 2 inputs the Chat ID and the Action, Both of these values look to be set and sent as part of the request. The addAdditionalFields function adds specifc fields to the request if there are any to add.

What is it that this PR is meant to achieve and did you test it before raising it?

[neoromantic]

Hey, thank you for investing your time. I have to come clean: I did not do it properly, did not test, just made an assumption that this is one-liner, and wasted some of your time. For that, I am sorry.

I've spent some time and done it properly now.

The purpose of change: support sending chat action in topics in Telegram. It comes down to adding one parameter to a query. It was almost done in existing code, but had not been enabled properly.

Currently there is no option to specify Message Thread ID (which is usually shown in Additional fields in other operations), there are not "additional fields" for sendChatAction.

My change:

• added "Additional fields" with "Message Thread ID" to sendChatAction operation
• fixed logic in addAdditionalFields to skip over replyMarkup logic if operation is sendChatAction

I've tested it in production settings in real telegram groups and it works.
