I'm doing a college project, but I've never created chrome extensions, The website is made in React and I need to run this code:
function placeMarker(a,b)
const element = document.getElementsByClassName("guess-map__canvas-container")[0]; // html element containing needed props.
const keys = Object.keys(element); // all keys
const key = keys.find(key => key.startsWith("__reactFiber$")); // the React key I need to access props
const place = element[key].return.memoizedProps.onMarkerLocationChanged
place({a,b});
I think this happens because Content Scripts are executed in an "isolated world" environment and I need this info from the website.
How can I fix this? I'm using manifest V3
I tried using chrome scripts but it didn't work well
