Can't get Scrape to work, don't know what I'm doing wrong

We have a little sensor, and I’m trying to get this value in to home assistant, but I don’t know what to do wrong.

When I use copy element I get “#mat-tab-content-0-0 > div > div > span.value-display” and my sensor is saying “unavailable”

Can someone maybe point me to what I’m doing wrong here?
