I am starting in development to create a Chrome extension and I would like to do like this extension on the first image. Unfortunately I can't find the name of this process. https://chrome.google.com/webstore/detail/dictionary-all-over-with/ahjhlnckcgnoikkfkfnkbfengklhglpg I wonder if it would be possible to have youtube tutorial or other examples. Currently I managed to display my extension during a right click by selecting text. I'm missing "just" the display when clicked.

chrome.contextMenus.onClicked.addListener( ( info, tab ) => {
// code
});
