• I have signed the Stream CLA (required).
• Code changes are tested

Description of the changes, What, Why and How?

This adds support for calling a new undelete endpoint, which can be used for undeleting previously soft deleted messages. The API requires this to be called from serverside clients and will return a 403 if called from the browser.

The API will also publish a new message.undeleted event when the message has been undelete. I'm not sure if more changes are required here beyond adding it to the event map.

Changelog

• Add undeleteMessage for bringing back soft deleting messages

The tests are failing here, but i'm not entirely sure why. Happy to fix if somebody can provide some guidance on what needs to be done 🙂

I see threads there. Perhaps @vishalnarkhede knows more about this one :)

We're missing a WS event handler here - is that expected?

Sorry, I'm not very familiar with this codebase. I didn't deliberately leave it out if it's required. Could you point me in the right direction, and I'll try to fix it?

Oh, no worries! I'm not sure what the specs are here but it should look something like this:

stream-chat-js/src/channel.ts

Lines 1272 to 1284 in cf27583

	case 'message.deleted':
	if (event.message) {
	this._extendEventWithOwnReactions(event);
	if (event.hard_delete) channelState.removeMessage(event.message);
	else channelState.addMessageSorted(event.message, false, false);
	channelState.removeQuotedMessageReferences(event.message);
	if (event.message.pinned) {
	channelState.removePinnedMessage(event.message);
	}
	}
	break;

@arnautov-anton thanks, that makes a lot of sense. AFAIK, the handler should be basically the same as for when a message is updated. I did some manual testing with this event sent from the API instead, and messages re-appeared. I added this ebb589f

Ignore the failing type test. I will fix those separately. You can even disable them for now.
