Issue setting up local development environment

I am trying use web sdk in my web app and trying this GitHub - DeepARSDK/shoetryon-web-js: Shoe try-on example app with DeepAR Web SDK shoe try on demo. It works fine on localhost but since I need to run it on my phone, i tried exposing my localhost using vite and it says “invalid Deepar key”, so I tried deploying my app on vercel and use vercel domain to create a key but even that is not working. So what is ideal way to setup development env. which can be used on mobile phone for testing?

We have a tutorial for testing with ngrok

We also no longer officially support user made shoe try on, check out our new try on plugin that drastically streamlines the process
