The only bit that is relevant to Drupal 11 is editing the info.yml file as it is compatible. There is no use of the mentioned library in the rest of the code and the spaceless in twig can be left for now.
I attach a patch to simply flag as compatible.

Remaining tasks

Consider raising separate tickets for the library and twig issues.
