⚠️

Actually custom variables is available only for iFrame and image format. As Google describe you can add a max of 25 variables.

import React, {useEffect} from 'react'
import fls_global from 'google-fls'
 
function App() {
    useEffect(() => {
        fls_global(cookies,{
                format: 'image', // or iframe
                advertiser_id: 8384813
            }, {
                type: 'test',
                cat: 'test'
            }, { // customVariables
                u1: 'qwerty1',
                u2: 'qwerty2'
            }
        })
    }, [])
    return (
        <>
            Test Application
        </>
    )
}
 
export default App;
