We have a SharePoint List in SharePoint Online holding max 1 element per User. Everyone can add only one element with his wanted settings. After that he is just able to edit his element.
The form was edited with PowerApps.
Now I want to embed this form in a SharePoint Modern Site. If there is no element in that list for the current user the form should be a "NewForm". When there is an element in that list it should be the "EditForm".
Hope to find help. Any questions will be answered! Feel free to comment.
