Hi Dylan,
I'm Amr, an independent advisor.
A wireless mouse connects with the matching wireless receiver (dongle).
Without the dongle, I'm afraid it will not connect to your PC.
Some mice have a Bluetooth connection, you can connect them via Bluetooth, unfortunately, your mouse does not support Bluetooth
I hope this is helpful. If you require any additional assistance, don't hesitate to respond to this.
Best Regard
Amr
