How do I send a function from content.js to the user's page in a chrome extension?

Question

When I do console.log(true); in content.js, the page's console displays true. However, when I make a function

test = () => console.log(true);

and then use the function in the page's console, it says that the function is not defined. How can I send that function into the page?

FULL CODE:

console.log(true); // prints true
var test = () => console.log(true); // console says test is undefined
window.test = test;

It still says that window.test is undefined, and test itself does not work either. — jackosaur, Jul 16 '20 at 23:17

you need to add var at the beginning of the function. And you have to call it as test()

var test = () => console.log(true);
test();
//should return true

Perhaps I have a fundamental error because that does not work either, test is still undefined. – jackosaur Jul 16 '20 at 23:36
var test = () => console.log(true) test() should log true – horrible Jul 17 '20 at 02:50
