How to get some text from using Web component?

[TechRead_Official (AppsAreGood)]

Good Afternoon

I wanted to change the website to get text from to Air Quality Forecast for New Delhi, Delhi - The Weather Channel | weather.com
I want to get this element

I tried to use document.getElementsByClassName("AirQualityMeasurement")[0].textContent;
But I always get null
My blocks

I did change the link to the new website link.

Thanks a lot!

document.getElementsByClassName(“AirQualityText–measurement–3ovem AirQuality–pollutantMeasurement–1g1Ns”)[0].textContent;

Tried it out. Turns out that it works perfectly. It does include quotation marks but I cut it out using some text editing!
