If a given dongle can be spoofed into providing arbitrary HID input (or just arbitrary keystrokes, in addition to mouse movement and clicks), that would be a more serious vulnerability.
Dongles of bluetooth keyboards certainly can input arbitrary keystrokes. That’s already enough to do basically anything on the computer. For example the tab character can be used to switch between different UI elements and exploits are usually carried out in code and not by manually navigating through files or windows.
