Hi @KacperKazan

Thanks for reporting this. The Agent Window file viewer currently supports text and image files. Video files and other binary formats aren’t handled in the file viewer yet, which is why you’re seeing the “Binary file is not supported” message.

Workaround: You can right-click the file tab in the Agent Window and select “Open in Editor Window” — this will open the file in a full editor window where video playback works normally.

I’ll pass along the feedback that video support in the Agent Window file viewer would be useful.
