I believe this could be used please confirm

/api/v2/routing/conversations/{conversationId}

We understand that a set skill action can be used while a conversation waits in a queue to add skills. We also recognize that you could perform this in a flow through a number attached to an external contact. We are looking for either the API being used for setskill action or an API that will allow us to do this in a live conversation. Hopefully, you can help.
