Using images in the app - storage permission


I am making an app where users can save their projects and edit them later on. The menu will show all their saved projects with an image of their canvas and the project title of each project. The issue is that if the user denies storage access, the image cant be saved of their canvas. Is there anything I can do or should I just use a placeholder image and just show the project titles.

You can use this topic … When the user does not agree to the permission, a message appears to him that he must agree, otherwise exit the application

Thanks for the link. i can do this without an extension though right? Especially since it is one permission only. Thanks for the suggestion to not let users use the app unless they accept. It would probably be the only way.
