How do you delete a portion of a video on an iPad?

I remember how easy this used to be in ye olden QuickTime 7 Pro on a Mac back in the dark ages. But I can't fathom how to delete a section of the video that I'm editing now on my iPad Pro 12.9".

I've selected the section of the video in edit mode, but can't find any option to remove it and then save the video with the clip (that has my login passcode in it) removed.

This used to be painfully easy back in Quicktime 7 Pro on the Mac, but I can't find a way to remove/delete a clip from a video on the iPad or iPhone.

Any help? Anyone? Bueller? Bueller?

TIA
