Good clarifying question at the end Scott- thanks for that. I've developed my app using a no-code app builder called bubble.io (https://bubble.io/home). So I access building the application through a browser. There are many individuals outside of bubble who have developed plugins and such for bubble and I had one such person build my app into what can be a mobile application downloaded from the app store. Sorry for the confusion. I was assuming that since I can share my application privately with others for testing through apple store connect that there would something similar for simulating that on devices without putting more code into Xcode. Hopefully this helps clarify why I'm not exactly great at understanding what I need to do while others who are putting their apps on the app store may not run into this problem.

Just to follow up ad hopefully get more help: In the simulator (as I've been doing it) I haven't been opening my app by clicking on it but by using safari to search for its url. I'm assuming my app is actually supposed to be on the simulator so that I don't have to go through safari to access it. So how do I do that? Or, to be more specific, how do I take my app from my app store connect page and make sure it is on the Xcode simulator so that I can get the screenshots I need. I'm not the best coder so honestly a step-by-step approach would be best.

So this is what I've been doing: Choose the view I'm wanting to capture Press Run/Play Once the view is generated, go to safari and type in the url. Capture the screenshots from the url. Once the view is generated my app isn't on the home screen so that makes me think I made a mistake in downloading xcode (or maybe just missed where I was supposed to enter my app into the simulator for it to populate). So uploading the screenshots themselves isn't the problem but accessing my application on the simulator is.
