Allow call queue extensions to sign in to app

Having the ability to sign in to the app as a call queue extension would be beneficial to those of us that have a call queue assigned as the Operator Extension and receive text messages to that call queue extension. In our case, we have all text messages sent to our main number directed to a call queue that alerts our help desk to the message. Previously, someone could use the (now legacy) RC Phone app to sign in as the call queue extension and access the messages to either respond or delete them; it was also the only way to send text messages as our main number. Now with the switch to the new RingCentral app, call queue extensions no longer have permission to sign in to the app, and therefore we cannot access text messages to respond or clean them up, or send them from our main number.
