If you see where LE are gathered together kind of under that tree - that is believed to be the area where Gabby was found. They're shielding her while other LE are setting up the canopy.
If you're talking about the group of people a few feet away from the canopy, they wouldn't hover over a crime scene like that, forever contaminating potential evidence.
In the 3rd video on this page, at about 1:10 into it, you can get an HD view under the canopy plus the area where the men were standing. There's nothing there. However, they walk off toward where I believe the body is, off camera.
Human remains discovered 'consistent' with description of Gabby Petito
