Hide Export to Excel feature for a specific group permission

Hello everyone!

I want to hide [Export to Excel] feature for a specific group permission. I have unchecked "Use Client Integration Features" in the group permission but nothing happens they still can export the list data.
Also I've tried the following CSS code but the problem hides from all users:

<style type="text/css">
a[id*='ExportToSpreadsheet']
{  display:none;}</style>

Since last week, I've added a code to hide multiple columns for a specific group permission but it breaks when exporting to excel that's why i want to hide this feature.

Is it possible to achieve it with a piece of code that hide this option for this library, and for a specific group permission ?

Any help will be greatly appreciated.
Thank you!
