Hi Dambé SANWOGOU,
Before going down the development path, have you seen the public surveys in Survey123? If you have and that doesn't fit your need, I would suggest that you start with the Quick Report. This will allow you set up your questions/fields in the feature service and away you go.
Good luck,
Gareth
Hi @gareth walter, I hope you found a solution, I also modified the code of my application by adding the url of my Survey123 form but nothing changes. The application opens with the Survey gallery
