BTT and Sidecar

I tried to search for it but couldn't find the answer.
I'm on a M1 Macbook air and a Ipad 9th gen. Both updated to the latest OS versions.
BTT Version 4.063 (March, 6, 2023)

When i use my Ipad with the sidecar feature enabled i can't seem to get the BTT Touchbar Customizations to work.

Should BTT work on the Sidecar Touchbar? if yes am i doing something wrong?
