The Buttons block allows you to add buttons linking to other pages on your site or to an external page. It’s great for calling attention to the most important thing you want your visitors to do.
Get started by clicking the + Inserter icon at the bottom-left corner of the screen and select the Buttons Block from the blocks list
Once you add the block it will add one button to your page or post and you can click on the + sign to add more buttons:
You can also click on the Cogwheel to change the button settings like text color, background color, border radius and if you scroll down you will find the option to add the link to the button
If you click on the ellipse menu you will find the options for the options to move the buttons to right and left when you have more than one button, copy, duplicate or remove the button
