Exit course query

I have a query on my Exit course button when I publish it on the LMS platform.

The LMS that I'm using is Learndash. I have created a custom Exit button on the last lesson. When the learners click on that button it should not open on a new tab but rather open on the existing tab which shows the tracking result.

Currently, when I publish the module and upload it on Learndash, it is opening on a new tab.

I have done a video recording on Peek for more clarity of my query.

Let me know what the solution for this is.
