Ruuvi tags over modbus

I am trying to integrate Ruvvitags into Home Assistant over Modbus but I cannot find the address in the CCGX-Modbus-TCP-register-list. I can use 3304 for temperature, but no Humidity, Accelerometer or battery voltage.

I posted a similar topic today, didn't notice this one. Supposedly humidity is 3306, battery voltage of the sensor is 3307, and pressure is 3308 - but none of those 3 work. I also found the accelerometers in dbus, but I don't see them in the modbus spreadsheet.

Do you find a adress space in Modbus for an 2. and 3. Ruuvi tag?
