Uning Catch Gallery

I am trying to create an image gallery on my website: pwaphotography.com. I am using Elementor to build the site. I have purchased Bold Photography Pro and added the Catch Gallery Plug-in, installed and activated. For the gallery I have created a page titled Black & White. I was able to add images using Elementor's standard gallery widget but I have not been able to figure out how to use the Catch Gallery plug-in. I read through the Support articles several times and tried to do the Edit Page => Add New Block => Formatting => Classic => Add New Media route but cannot find those options on my Dashboard or Menu bar. Keep going in circles that lead no where. I can add a new block to the page with Elementor with no problem but then what do I do? Shouldn't the Catch Gallery plug-in show up in the widgets gallery on the left sidebar? Or shouldn't I be able to open Catch Gallery from the Dashboard while on that page and add images? Seem to be missing info or a step. Thanks! Peter
