How to get running query text

My first post here. 

I should get the query that arrives to the SQL SERVER database created by an application (reports).

I should automate some of those reports and I need to get the query which is running so I can then try to create a script with that query.

I'm completely new to SQL Server and having a lot of experience in Oracle. I'm using SQL Server Management Studio 15.0.18206.0 and

select @@version

give me this result: Microsoft SQL Server 2016 (RTM-GDR) (KB4019088) - 13.0.1742.0 (X64)   Jul  5 2017 23:41:17   Copyright (c) Microsoft Corporation  Standard Edition (64-bit) on Windows Server 2016 Standard 6.3 <X64> (Build 14393: ) (Hypervisor) 

Can you help me please ?
