Passwordless auth: Custom sms provider with twilio verify

More then a year we used passwordless auth with twilio, everything was good. But now because of this it stopped working, so we want to move to the twilio verify. From the docs it’s not very clear how to do Set Up Custom SMS Gateway for Passwordless Connections

Also I saw this and if this answer still true (no Basic auth support from the auth0) Custom sms provider then I guess it’s not possible to do using custom sms provider. Is there any suggestions or options?
