SMS Campaign because no way to text OTP

My SMS campaign tells me that because I'm a sole owner I will need further verification. They will send me an OTP via text messaging.

I have not received a text message and I assume this is because I don't own a US number. Because the campaign required a US number, I put the phone number that I have just registered through zoom. Obviously, text messaging hasn't been set up yet fgor this number.

My regular phone is an Australian number which is on my Zoom account profile. How can I get past this?
