Support for Moodle 5+

Dear @dbnschools , @golenkovm and @bilo1967 ,

as Moodle 5 is already released and Boost Union also supports Moodle 5 it would be great if your plugin could be enhanced, too?!?

For instance ist the Teacher Course Management Dashboard not working and maybe some other, yet not identified issues, may be to be identified.

Thank you in advance.
