Javascript popup

How To
1

Where I can find a full documentation of opening a popup using javascript?
I have read “Popup events & helper functions”, but I cannot find the way to apply
a) action (like start animation) and b) animation (like fadeInUp)…
Also, what is the second parameter of bricksOpenPopup(popupId, 0, xxx)

Only as an example:
As AJAX is not working to get data from Metabox.io with Bricksbuilder, I built it myself, but now I want to achieve the following:

            // Call fetchData function (fetch and fill innerHTML)
            fetch_restAPI_data(); 

            // open the prefilled animated popup
            let popupId = 1234;
            setTimeout(() => {
                bricksOpenPopup(popupId, 0, {
                    popupContextType: "post",
                });
            }, 100);
