Restricting Users to Create Sharepoint List Entries Only Through Power Apps

I'm currently working on a project where I have a SharePoint list called "Inspection" and a Power Apps program that interfaces with this list.

My goal is to allow users to create entries in the SharePoint list exclusively through the Power Apps program, whilst preventing them from manually creating entries directly in the SharePoint list itself.

To facilitate the creation of new entries, I have set up a Power Automate Flow that triggers when users submit data through the Power Apps program. However, I have found that in order for the flow to work, users must also have the permission to manually create entries in the SharePoint list, which is not ideal for my use case.

I'm looking for suggestions or alternative approaches to ensure that users can only create entries in the SharePoint list through the Power Apps program and not directly in the list itself.

Is there a specific permission setting, configuration, or workaround that I can implement to achieve this?

Any guidance or suggestions would be greatly appreciated!
