Hi @astrontelstar
Because you have mentioned it is a dataverse backend. Here are the top-level principles to achieve what you are expecting.
1. Create a Power Pages (Portal) first and enable Azure AD login. Remember you can turn off the local login as this will confuse the user.
2. Place a link in your power app to the newly created power page.
3. Once they click the link, they will be prompted to sign in. As we only enabled Azure AD, the only the first time they need to sign in, after that they will be auto logged in upon clicking the link.
4. Design a page and add a table and link your existing dataverese table ( orders table). Use filters and filter by username and show the data according to your scenario.
Have fun. Hope it gives a high-level idea.
Hope it helps.
