How do I automatically scroll to the top of the frame after it is cleared?

I have a screen that I load a bunch of data to via excel. Then I have the option to clear the screen and do it again. The problem is, when I load again, if the frame was not scrolled back to the top, the screen is laggy and jittery until it gets back to the position it was at, or until the excel file is finished loading.

What I want to know is what do I need to add into my clear function, to reset the scrollbar to the top of the screen so that this does not happen anymore.

This minimal reproducible example just shows the scrollbar not going to the top when the screen is cleared.

Thanks
