So, I've been playing around with the V2 Approval actions and noticed that the Create an approval (V2) action has an output that is "Adaptive Card". For a long time, I've been looking for a way to resend an actual Approval email as a reminder. Currently, I'm sending the Approver a link to the Approvals > Received page in Flow, which works, but isn't perfect. What would be perfect is resending the actual actionable message/adaptive card.
What I've tried is using the generic Mail connector to send the reminder and adding the "Adaptive Card" dynamic data to the message body. What I get is this:

So, clearly this is not HTML. I think it's JSON, but not sure. I'm even less sure how I could go about adding it into an email. I assume the original/actual Approval message has a header or tag that goes around that to format it appropriately, so I either need a way to include that in the HTML message or we need a new action ("Send approval notification") that takes the Approval ID of the Created approval.
