One of the things that social networks allow you to do with a native application is to be able to select the preview image that a video can have when it has not yet been opened.
This is very useful to be able to draw the attention of users and invite them to watch the video when it has not yet been opened.
Otherwise, if you can't select the video preview image manually, Hubspot selects a random image, so many times it can look weird if you grab a frame ramdon
Thank you very much, I hope you can implement it
Greetings
