Manual Domain Validation Request - ngrok

I need manual domain validation. My app “Testpress Live Learning Suite” is already publish and to test out the production environment in local I need domain validation for ngrok-free.app. This will help our internal team to test production zoom app locally. My url https://egret-solid-gazelle.ngrok-free.app/

The domain registered in the Marketplace is ngrok-free.app, which is ngrok’s infrastructure domain. I do not control the root DNS of ngrok-free.app - Ngrok (the tunneling platform), so automated HTML file verification and TXT record methods both fail as ngrok has a verification page which is blocking both the HTML file verification and TXT record methods.
