Doesn’t work, no documentation

It’s possible to link to the Square APi, but that’s it. The form does nothing , does not display using the shortcode, there’s no gutenberg block of any kind and there’s no documentation for this version – everything is a link to the Pro version which has a different interface. So all this does is connect, then that’s all. No ability to create a form which will show up anywhere, and no docs to user- trouble shoot the absence of function. It’s a non starter.
