Installing Canvas Library in hassos

Hi,
I am using Node-red add-on. One of the nodes, which is a integration for ECOVACS Deebot Robotic Vacuum cleaner needs Canvas library to be installed to get the current room being cleaned. How do I install canvas library in Hassos?. Is there a add-on which uses Canvas Library so that it I install the add-on the Canvas Library gets installed. A roundabout way of doing it.

Did you ever figure this out?

No. I have installed it on an additional raspberry Pi and using node-red with it.
