I have resolved the problems yesterday, and refactor the tabs, now it's ready for testing.
before testing, there are some works

  1. create an website for the privacy-and-terms using this link
  2. deploy this website on Cloudflare Pages
  3. using another app to test deeplink

Result:

  1. I found That I can't testing the deeplink jumptation between app in the emulator, I will tested it in real device.
  2. I also find that I need to add edit and delete function of submissions, and intregrating deeplink in use's app is too complicate and not everyone want to do this, I need to make it easier of verifying testing behavior, they can just upload an screenshot
