The back button needs to bring the user back on the dashboard menu since the user has chosen the webinar from the dashboard, instead to do so, the site is leading the user to the webinars area.

1. Navigate to: https://qainterrapt.brainster.xyz/dashboard
2. Choose one of the webinars
3. Click on the "Back" button

Expected result:
After clicking on the "Back" button the user should be redirected to the dashboard, where the user has chosen the webinar.

Actual result:
The "Back" button is redirecting the user to the webinars site instead of redirecting him to the dashboard.
