There's a Juce classes to do that :

This is a specialized TextEditor + Button.

Just add a listener to your component to interact with the user :

https://www.juce.com/doc/classFilenameComponentListener

class MyComponent : public Component
                  , public FilenameComponentListener 
{
    public:
        MyComponent ()
        {
             addAndMakeVisible (filenameComponent = new FilenameComponent(... [param] ...));
             filenameComponent.addListener (this);
        }

        void resized () override
        {
            filenameComponent.setBounds ( ... [bounds] ... );
        } 

       void filenameComponentChanged (FilenameComponent* fc) override
       {
           File userSelectedFile = fc->getCurrentFile();
           String userSelectedFilePath = userSelectedFile.getFullPath();
  
           ... [do something with the selected file] ....
       }

    private:
        ScopedPointer<FilenameComponent> filenameComponent;
};
