Base Extension - Method - Customization

There is a Dashboard called Wait list, which has the Base Extension.
Base extension code has a method called- CallDynamicQueryAdapterUpdateMethod.

private void CallDynamicQueryAdapterUpdateMethod()


I am not able to call this method from the Customization code. Can you please suggest how to call the method CallDynamicQueryAdapterUpdateMethod() written on the base extension from Customization Code?

I don’t usually use modified base extensions, so I may be wrong here, but I would assume that the private access modifier would make it inaccessible from a customization layer.
