Javascript Toggleable Function-CodePudding

I am currently making a function where if you click this div element, an svg element will show up inside the div by using the innerHTML but when you click on it again, that element will change to another svg, so basically, I want the function itself to be toggleable. How can I make it work?

You have to add an event listener on the button.
