In my case, I’d like to split the 56 minutes video into two parts, roughly 28 minutes each. To split or trim a given video just click “Trim” and use the handle to select the range of your new video clip. Notice that there is an icon Trim if it’s rendering a video. Only this time, the app will have additional controls on the top navigation menu. This will render the video in a different app, very similar to Movies & TV. You can select the video and go to Open (or right-click Open with …) > Photos & Videos

To view and edit the video, you need to open the video in another app called Photos & Videos. This app doesn’t do anything other than playing and render the video you have selected.

Depending on your default settings, a video might be opened in Movies & TV app by default.

It’s a feature existed in the Photos & Videos app, instead of Movies & TV. In Windows 10, if you want to trim or split your video into multiple parts you can now do it natively without any additional third-party tools.
