What package/app is actually running when doing dialer codes

I am currently trying to figure out another way to access my Samsung Galaxy S21 Ultra's Secret Menus accessed via the dialer codes. My phone cannot open almost all of the dialer code, probably due to restrictions. I figured out how to open the Phone info(The one with the preferred network Setting) menu via an intent, but I'm now trying to look for the other ones like 4636 and 9090 I then realized I just need to know the package and the class and that stuff to open it. The question is, what are the packages. I'm basically looking for what package is opening all of these secret menus, and how to execute the dialer codes through that package via intents, or if there is another way to open these secret menus without the dialer. Please know that I don't actually code intents and use something like automate or Macrodroid to run intents. I am on a un-rooted device, and have no way to access adb. Basically what I'm doing is trying to configure stuff with 4g/5g while just seeing all the menus and what they offer. Any help would be greatly appreciated!
