How to close the popup window after submitting a CRM form?

Question

Layout

I am creating a website in the "Bitrix24 Sites" constructor, I ran into a problem: there is a block with a regular CRM form, but after clicking on the "Submit" button, a window pops up over the form ("Thank you, your message has been sent." or "Unfortunately, the message failed submit. Please try submitting again later.") does not close in any way until you reload the page.
Is it possible to make the pop-up window disappear, for example, after some time, and again give access to filling out the form?
I looked both in the form settings in the constructor and in the form settings in the CRM form section itself. Unfortunately, I am not a Bitrix programmer, but just a layout designer interacting with the site builder, so I can’t get deep into the form code. But if there are solutions that use additional CSS - they will work too.
The form after submitting the application looks like this:

I did this: in the CRM form settings, I enabled a redirect by a link in 1 second to the previous page or to the main one.
upd If you redirect to the page with the form, it will mislead people: did I submit or not :/
