IMO, my first idea about this feature is to place it in the message buttons menu and integrate in message editing feature when being used on a Thread message.

Given that the chance to insert the input field inside message body has been rejected :/. I would suggest to at least render in the new message input but I am not sure how it should look like.

I had similar thoughts as @DorraJaouad . We should allow editing the message as well, and if it is possible rn it doesn't seem obvious.

My idea would be to rename it to "edit thread details" (any better wording ideas anyone?) and allow that from 3 points:

• in the conversation when you are outside a thread, we can have it as an action in the message actions menu, and clicking on that would allow you to edit title and description like how a normal message is edited
• inside a thread we can have a 3 dot menu in the header, and clicking on that would again allow you edit like a normal message
• in the list of threads on the left, we can have in the action menu like in this PR, clicking on that would open a modal with title and message which we can edit and save

What are your thoughts?

• would be fine to rename existing button for 'Edit message' -> 'Edit thread details' then?

I'd prefer to unify both with a dialog or popover, whatever fits best. And these two should not affect first message, as it's:

• can no longer be edited (after 6 hours)
• is not visible in both these places

Yes, for threads it can be "Edit thread details" and for regular messages "Edit messages" :)

Works for me 👍🏼 we can do a dialog as the message may be long and fitting that into a small popover may not be the best idea.
