Hi Team,
we have custom app which was designed to post messages on existing web message conversation , where us we are getting error while using this API with Oauth - Grant Type -Client Credentials with all necessary permissions

/api/v2/conversations/messages/{conversationId}/communications/{communicationId}/messages
Error-
-{"message":"This request requires a user context. Client credentials cannot be used for requests to this resource.","code":"bad.request","status":400,"}
Is this platform Api defect ?
