View Rights with specific Link

Hello,
I have a Share Point where I save Data from users which can add and change data with a Powerapp and now I want to add that users can got to the SharePoint and can view everything.

Now is my Question if it is even possible to let still the people add and change the data over the Powerapp and be able if they use a Specific link they can only view the Data?
Best wishes and Thanks in regards
