Bluetooth Pairing of Corsair Harpoon RGB Wireless with iPhone X

I'm trying to pair my Corsair Harpoon RGB Wireless Mouse to my iPhone X via Bluetooth for accessibility purposes and can't seem to get it to pair. First I set my mouse to Bluetooth-pairing mode by holding the DPI selector button and switching over to Bluetooth mode until the indicator started flashing blue to indicate that it was ready to pair. Next I attempted to pair with my iPhone X. I originally tried via the iOS Bluetooth settings and it says pairing took too long. Next I tried through the accessibility options specific for pointing devices and it got stuck in an endless loop, seemingly attempting to pair but never actually succeeding. How can I successfully pair my Corsair Harpoon RGB Wireless Mouse to my iPhone X to use as an accessibility pointing device? Thank you in advance.
