Open / Close Javascipt button

Hello everyone,

We are customizing the career site for the client.

We have added some javascript code to the site in order to display a button created and inserted by us in the preview of certain job requisitions.

However, we do not have to implement the function for opening and closing the chatbot on the button.

As we go back to the click to view the chatbot inserted but by clicking again on the button a new chatbot visible at the end of the one previously created is recreated.

Could you give us some more information about it such as the implementation of the function to open / close a page with the same button?
