"Create thread" response type for interactions

[prryplatypus]

Hi, I would like to ask for the ability to create a thread in response to a message application command while authorised with the application.commands scope only.

Since this type of command (type 3) is always bound to a message, it would be nice to be able to create a thread in response to an interaction and respond in it without needing to authorise the application with the bot scope. Of course, the application would still be restricted by the @everyone permissions in the channel (so would need permissions to create threads).

An example of something where this could be useful is a command with which the message is cross-posted to an external source, and you'd want to link the message to that external source.

For safety's sake, this response type should be gated behind MANAGE_CHANNELS.

what about MANAGE_THREADS instead? it would make more sense

Or just... create PUBLIC/PRIVATE threads, bc that's what they're for? :D
