DevTools: Inspect can be used by the following steps: Click on Your right mouse button aka RMB on something. (2 fingers on your screen with a touch screen device.) And go to inspect. Yeah, i hear your confusion level raise a bit. Those are Scripts, you can temporarily and only see able for you, EDIT THEM, sort of.
Does it have Text Follow this, and if it is an image, we are getting onto that later. Look at what you selected as the something i was talking about. What did it say? Look for that in the script, if you cant find it, click on the arrow behind the script. Type in the text you want! If you refresh it's gone by the way, and other people cant see it.
For the people that got an image, here you go: Go onto a website like Imgbb to upload the image you have on your computer, then take the link of that to your script (make sure it says img src: link) change the link part to whatever your link of your image was. And boom, you have gotten your image for yourself temporarily.
This is not done, if you have any info we missed: Edit the page here: https://google.fandom.com/wiki/DevTools:_Inspect?veaction=edit
