We recommend you to search the mailbox with the following subject lines:
Someone requested your event's access
Someone requested your company's access

Tip: OTP is generally sent as soon as you click on Send OTP button. It might be due to some firewall network security in your office by the IT department. You may either make changes to your firewall settings and then again request for the OTP else you may try using a different method.
