PWA Text Cleared and PWA Install Text Edit

Good day Team Wisej,

I have this requirement from my client to clear the “Wisej PWA-” text that appears as part of the form header when the app is installed, as shown in the attached file.

For the second attachment, they would want to see the name of the application, such as “Open GridApps PWA” instead of “Open with Wisej PWA”.

The third issue has to do with the shortcut created on the desktop after the app is installed. I would want the application icon and name displayed instead of “Wisej PWA”  as seen in the 3rd attachment.

How do i achieve these pls?
