Thanks @rich2005
I used a software called Axialis Icon Workshop. When I exported as ICO, it works fine for the same image except for List and Details in Windows 11. So it has to be something related to the Iconify script. I am thankful that it exists and gives very close to what I want. But if it can be precise somehow, it would have been nice. Axiailis is paid software. I am using the trial version now.
I was making those in Ubuntu. I am helping others with custom icon requests, for free.
