Problem with Zapier and blocked domain

Hello,

I was trying to create a custom Zapier from ACP and I got this popup warning me that my domain is blocked.

When I go to Zapier or click on the ADD DOMAINS button. I want see the Settings --> Embedding Domains anywhere :(

This is what I see when I click the button. Nothing in settings. Anywhere. See the screenshots. That popup is directing me to a place where there is no option to embed any domain. I looked in other places, and nothing. Do I really need to do this? If so, where?. Or is this only for completely new Zapiers that do not exist? Thanks

I also see this, nothing about the embedded domains either.

Nothing here either:
