Accessing Android from Windows via KDEConnect: Additional Android App required? Existing adb.exe usable?

I am searching a Windows tool which let me copy/move/rename/delete files on my Android device based an ADB protocol rather than MTP.

Does KDEConnect require (in addition to the Windows tool) a Android App?

I miss some snapshot how KDEconnect GUI looks like on Windows.

Does KDEconnect come its own adb.exe or can I use my existing ADB Tool Platform installation?
