Sidekick sidebar also as Off-Canvas

drupal-off-canvas is deprecated
Follow the link: https://www.drupal.org/node/3305664 → to support off-canvas dialog before and after D10.

I have the same issue on my module 📌 Chat in the sidebar (drupal off-canvas support) Active .
Summary:
* Study how webform module has done it, because it looks very good compared to default.
* Also note that other Drupal features may want to use off-canvas at the same time.
Overall off-canvas is great to do.
