FOR HELPINGWoah! Great Work 
, I was searching for the same kind of extension in community for a very long time, and I finally found it, I tried it and it’s easy and very simple to use. Even though using it as an OTP sender to make OTP verification app is better than using firebase, It has customizable template and is having a very low price too, Thanks for helping community with it, we do appreciate your work.
Thank you.
