Hello! Could you send me a link to the website? Do you mean, user will see this pop up when he first time on the website ? ( it will not appear after go to another page, refresh the page and so on)
I am a Front-end developer and i can build apps using technologies like: React, React Native, Firebase, MongoDB , Redux, react-i18next, Ajax, google-map-react, react-bootstrap, react-router-dom and so on.
Thanks.
