Not receiving SSO invite emails

I am attempting to set up SSO with my Gsuite and AWS. I have followed the following blog to do so: https://aws.amazon.com/blogs/security/how-to-use-g-suite-as-external-identity-provider-aws-sso/

After I configured my user, I received an invitation email from AWS on my Gmail. I clicked it to accept the invite. I later discovered that I misconfigured the SSO endpoint, and deleted it along with all my users.

I have since created a new SSO endpoint, and invited myself using my Gmail, but am not receiving another invite email from SSO. Do I have to wait some time before trying again? I have verified there is nothing in my spam or trash folders. I'm worried that my email is now attached to an SSO endpoint that no longer exists. The email is Panoply@merstab.com . Thank you for any help you can give.
