Fade in/out a 2D Video Clip

Super new to UE and working on creating a 360 video. I have a level in place and want to have a few 2D video clips fade in and out of the environment (as an example: imagine standing in a space and having a few different news clips fade in and out in your field of vision).

I followed this tutorial and have a video that plays in the environment with sound:

I cannot figure out a way to have the plane the video is on to fade in as the video begins playing. I assumed it would be an easy thing to do in the Sequencer, but I don’t see opacity controls anywhere.

Any suggestions?
