justboom remote

Hi,
first thanks for all the work!
I have another question, im using picoreplayer with a justboom DAC. Now i would like to use the remote (https://www.justboom.co/product/justboom-ir-remote/) with it.
I dont really understand what im doing, maybe someone did install this very remote already and can guide me through?! It works with volumio, so the hardware should be connected right.


Thanks for your help!!!
