How to create constructor of ThisAddIn class in VSTO

Using VS2019, I have created a VSTO AddIn WORD project. As we know the default template of this project creates a ThisAddIn class with two events ThisAddIn_Startup and ThisAddIn_Shutdown but no constructor. But when I try to create a constructor of this class as follows, I get the following error:

public ThisAddIn() { } 

Error:

there is no argument given that corresponds to the required formal parameter 'factory' of 'AddInBase.AddinBase(Factory, IserviceProvider, string, string)'

Question: What is the cause of this error and how can I create a constructor in ThisAddIn class?

Some Background: I am trying to mimic functionalities of a Winform (Windows Forms) project into a VSTO office project. The Winform project has some code inside its constructor Form(){...} that I need to implement inside the constructor of ThisAddIn class of VSTO projects.
