HI anushas0002 as per my understanding This Integration Object invokes an API of type GET call (as you want to retrieve complete details). You can invoke this Integration Object in following ways: 
 
1. Upon load() 
2. using saveInto 
 
If you want to query the information using Integration Object while clicking on a button, then you need to make a call to API using this Integration Object under Button saveInto. Now it all depends upon your business scenario, whether you want to make this call conditionally or unconditionally.
