For the next googler who lands here. The last version of the module compatible with PHP 7.3 (yup, sometimes you find yourself stuck upgrading super old projects) is version 6.0.3 (6.0.3) →

The project, starting from 6.0.3 requires then the module jquery_ui version ^1.6, which on it's side requires at least Drupal ^9.2.
