MFA authentication is not sent to Cloudflare

[nickali]

I've got a Cloudflare protected site that uses Authentik in the front. When Cloudflare only requires certain emails, everything works great.

Now I want to require MFA/TOTP. I've added the requirements on the Cloudflare site. I've added TOTP to a user on the Authentik side. When I access the protected site, I get authenticated by Authentik and then I receive an error on the Cloudflare side the user does not have permission to access the site.

Is there something I must set so Authentik will provide the MFA verification to Cloudflare? Like a claim?
