Zoom Phone Text Messages

Hello! My company just switched from phone.com over to Zoom Phone, and people are loving it so far, but we've run into a major snag. We used to have two-factor authentication set up everywhere to send a text message to our company number, which would then forward to an email address, and then that email would auto-filter into our company's Slack, in a specific 2FA channel. With the switch to Zoom Phone, I can't figure out how to even set up text messaging so that more than one person can access these messages, and this has become a problem.

I currently have an auto receptionist set up for the company number, but when I assign a user to the Power Pack license that we have to test, text messages still do not come through to that user when texting the company number. 

Please advise!!
