Trying to lunch my app through Appium's client with no success

Hi All,
in the Appiums’ client settings I have configured the app’s apk path, the package and activity , and thicking “ON” the radio buttons next to each option.
but, the app is not lunching, while running it through my code(C#) and settings those settings in my capabilities, app is lunching just fine. is it even possible to lunch the app through the client?

my second issue is that I would like to keep session opened without starting it all over again when running my code. I would like the session to be alive and test a page while it’s opening. is it a possibilty?
