Hi,
We have a requirement to set the first frame of video assets as thumbnail for that video asset when we upload the video asset. I referred this document to set it manually after the video is uploaded and processed.
I have enabled the dynamic media but the change thumbnail button in not showing as in the video bcz it is disabled in this path "/etc/dam/dynamicmediaconfig". How to enable and see the button?

Also, do we have process to set the thumbnail via java code or config when we upload?
Thank you.
