Press Add video
In the following pop-up you should be able to choose the video you would like to use. After having uploaded the video and pressed save your learners should see the video by default the next time they log in.
If your video is bigger than 40Mb then we recommend compressing it for example with an online tool like Veed: https://www.veed.io/tools/video-compressor
