I am making a Chrome extension that adds a button to a React page (whatsapp web). And I want this button to call an existing function, exactly as another already existing button that is inside a menu.
My extension was built using React.js too.
What I already know, is that that existing function is named handleSelectMessages() (I used the React Developer Tools to see that), but I cant find a way to call this function.
How can it be made? (Keep in mind that I cant make changes to the original react page, I can only inject new js)
I`ve tryed the very basic:
<button onClick={() => handleSelectMessages()}/>
But as expected it didnt do anything.
I`ve tryed also:
<button onClick={() => window.handleSelectMessages()}/>
But it seems it is not avaliable globally.
