The missing requirements section leads to an accidentally installed module, which will not work, without to install additional other modules, which are in fact not part of a standard Drupal 9 installation. If one doesn't like the missing modules, he needs to uninstall or delete this previously installed module.
Install it on a freshly installed Drupal 9 site and show, which other modules are required ... (jquery...) ...
Pleas add the required modules under Requirements in the Drupal modules installation description.

Documentation
Primarily changes documentation, not code. For Drupal core issues, select the Documentation component instead of using this tag. In general, component selection is preferred over tag selection.
Not all content is available!
It's likely this issue predates Contrib.social: some issue and comment data are missing.
The above changes looks good to me, the documentation can be updated.
Documentation for this project needs to be converted which will cover in #3047764: Update Better Exposed Filters Documentation → .
README has the dependencies right now.
