Cognito 2FA and registering a 10DLC campaign

I'm using the Cognito hosted UI and want to enable 2FA. I can't update any of the 2fa language because the hosted ui handles all of that.

I keep getting my 10DLC campaign rejected due to: "Opt-in process not compliant or opt-in is not explicit".

This is what I wrote for the opt-in flow: "When signing up, they are directed to a screen that asks them to enter their phone number with a "SEND CODE" button. Pressing send code is the user's way of opting in to recieve to 2FA code from us."

Is there a workaround here? I've tried a few different descriptions and I don't know how else to fix this without having control over the 2fa screen text.
