When a text message is received, the notification email refers to the RingCentral app for replies:
"To reply using the RingCentral app, click here."
If an additional reference and link to using the RingCentral webpage for replies in lieu of the app could also be given, it would be helpful for those unable to install the app. Non-persistent virtual desktop users for example. It could say:
"To reply using the RingCentral webpage, click here."
