Now go into the page you want to display the schedule on and enter the shortcode
[mak_jr]
where you would like to see the table (procedures vary depending on the page builder you use) and preview or publish the page and you will see your default list. Without filtering and changes it should be the same information as you can see when going to https://app.jackrabbitclass.com/jr3.0/Openings/OpeningsDirect?OrgID=XXXXXX - where you replace XXXXXX with your OrgID.
You can then add any other filtering or display options as you wish either in the defaults or in the shortcode.
You can use the shortcode helper in the WordPress admin panel under Tools->MAK Jackrabbit Shortcode Helper to build a shortcode, check your filtering or view all available classes, and experiment with settings to find your preferred default settings.
