Popover opens first (after 1 second).
Sidetab opens second (after 6 seconds). However, if you closed the popover before it opens, the sidetab does not open because they both show the same typeform.
If you closed either popover or sidetab, neither of them will open on page reload.
Regardless of your previous actions a popup opens third (after 7 seconds). If you close it, it will not reopen on page reload.
