When in mobile, there should should be two buttons at the bottom of the page:

1. DONE
2. gray state when the button is invalid (see desktop version for validity parameters)
3. normal state when the button is valid
4. on click: confirmation dialog (see T306265) and
   • if "DONE" selected, go to to view function
   • if "CANCEL" selected, close dialog

2. Implement function
3. gray state when the button is invalid (same validity parameters as done)
4. primary state when the button is valid
5. on click: confirmation dialog (see T306265) and
   • if "DONE" selected, go to implementation page (NOTE: there are no mobile mocks for implementation page yet)
   • if "CANCEL" selected, close dialog
