Integrating SMS OTP by ApiStack

Hey everyone, I need some help integrating the SMS OTP plugin, has anyone had an experience with it? What’re the steps to integrate it into my application.

Also looking for some assistance, the apistack tutorial for bubble integration is still not available.

The tutorial is here: Phone Number Verification using SMS in Bubble App - YouTube

But seems like it doesn’t work currently. For a week already I do not get SMS with OTP. Anyone having the same issue now?
