I am adding a new mail account to Zoho MAIL choosing to add my GMail account via IMAP.

I follow the screen to add the GMail account and I get the following error. There is no issue with the password as it was checked independently. I do however have 2FA set on the Google Account.

I already have the GMail account set in the CRM as IMAP but am wanting to move to MAIL for managing emails as Salesinbox is unsuitable.

How do I resolve this as all other posts seem to be a failure about reading Zoho mailboxes through GMail whereas I am going the other way...

TIA
