I need to understand how Arguments for link types work and where can we find them

[NouamanD]

Hi All,

I am new to the platform and while i was discovering Apps Navigator I noticed :

under Application menu "service desk" - "Knowledge" - when i click it, it brings me to the knowledge bases page

when i go to the settings of the Module  I noticed Link type and arguments, i cannot seem to understand where they got the argument from? see attached screenshot

Link type: URL( FROM ARGUMENT:)  

Arguments: knowledge_home_launcher.do

The reason why I am asking is because i want to test create an Application menu and Module so when we click on the Module i will create i need to know where i can get the Arguments to put it in my module something like the above : knowledge_home_launcher.do)

I checked other Modules and there are other type of Arguments i understand the argument tells the on click event to go to a specific page but i want to know where are these argument located or if i have to create them my self please point me to a learning ServiceNow link where can read about it .

I am newly CSA certified and I am practicing , I am not sure if these Argument and Link types applied to Admin role or developer roles

Please advise
