Polychromatic uses options from what is available from OpenRazer. This app intends to stay focused on lighting management, and OpenRazer's scope is more device-specific enabling functionality. So, since it's just another mouse button, it would be more of a button remapping thing. input-remapper exists for that, but doesn't support scripts/code from what I know.

A script can be easily put together to toggle DPI using OpenRazer's Python library:

#!/usr/bin/python3
import openrazer.client
import os
import sys

devman = openrazer.client.DeviceManager()
mouse = None
for device in devman.devices:
    if device.type == "mouse":
        mouse = device

if not mouse:
    print("Mouse not detected")
    sys.exit(1)

current_dpi = mouse.dpi[0]

if current_dpi <= 800:
    mouse.dpi = (1600,1600)

elif current_dpi <= 1600:
    mouse.dpi = (3200,3200)

elif current_dpi >= 3200:
    mouse.dpi = (800,800)

os.system(f"notify-send 'DPI Changed' 'Now set to {mouse.dpi[0]}'")

I haven't tested this, but each time the script is run, it'll switch DPI to the next value (800 → 1600 → 3200), then wrap round again. Plus it'll show a notification (if notify-send is installed)

Just needs a way to trigger that script - try installing/setting up xbindkeys. Let me know if you need more details on how to do this.

Hopefully this solution works for you. The whole remapping buttons is like reinventing the wheel, a burden to support (e.g. X11 vs Wayland), and doesn't align with long-term ambitions for this project.
