Hi,
I have checked your video, thanks for sending it to me. Unfortunately, I am still unable to understand which delay you are pointing to. The form page you have shown in your video is getting in from the bottom up fashion and pretty quick! It is the style of this bottom up animation.
However, if you are interested, would you please check out our interaction feature to see if it is suitable for you? Here is the doc link:

Let me know your opinion.
Best Regards
