Dear SangPhan87 - we had custom icons for QuickFolders users until Thunderbird 102 - this feature has to be (and will be) rewritten for Thunderbird 115, if it is possible.

You can already modify the color of folders in Tb115 via Right-click / Properties as a built-in function. Please add new feature requests on the QuickFolders Github for a bigger chance of being seen and implemented.
