Hi Naomie,
I am a Xerte developer and yes, Xerte uses Tsugi, but Xerte does not use Tsugi cloud, but incorporates Tsugi as a subsystem. You setup the connection between Xerte and Canvas using the Tsugi admin panel of the Xerte installation (https://<xerte url>/tsugi/admin).
Please note that Tsugi is not installed by default in a Xerte installation.
I see that you work for Drieam (you have a
drieam.nl email address). You could ask the question on the Xerte forum (
https://xerte.org.uk) or contact me directly.
With kind regards,
Tom Reijnders
