Video link and embed issues from office 365

Dear support!

I have a website with learndash plugin. When i would like to insert a video from office 365 in a learndash lesson it wont show or couldnt play the video. I tried self host url, that case the video has a grey background and cant play, than i tried to embed a html code, but that method unsuccesful too, because the user had to log in to watch the video. By the way the videos type mp4 and shared by open source. I didnt find solution all around int the internet. Any solution?
Best regards, Erik.
