Auto scroll after adding to cart

On demo.joomdonation.com/osservicesbooking/...ointment/hair-cut-13 page, when I add an item to cart, the page automatically scroll to the top to show checkout button. The problem is that, the checkout button (along with the message) disappears in a few seconds.

(1) Is there an option to not disappear that message-with-checkout-button?

(2) Which code (I need the file path only) can I modify so that instead of scrolling to the top, it scrolls to the bottom?

Hi,
You don't want to show the message at the top of booking page after adding timeslot, right?
Thanks

I want to show it. I would like it to stay there, but currently, it disappears automatically after 2 seconds.

Hi,
Currently, the message is showing in 5 seconds, maybe i will extend that time and make it longer.
Thanks

Is it somewhere in the file that I can simply increase for now? If so, can I know the path of the file?

Hi,
You can open file: root -> media -> com_osservicesbooking -> assets -> js -> ajax.js
Find:
5000 and replace by 10000
Thus, the message will be kept for 10 seconds
Thanks
