outlook - How to use custom attributes in an e-mail template (outlook)?

Question

I want to send mails through a PowerAutomate Flow. For different email-addr I would have different email text-templates and some of them should use custom attributes.

1. how to access custom attributes in the powerautomate action "send an email"
2. how do i distinguish whether the user of the email address has custom attributes at all or not?

thanks
