I have an extension Magestore_Bannerslider, which the previous developer installed using composer for magento2, The module is installed and working properly. The code is in the vendor folder
I need to add some custom code in the module but i do not want to edit anything under vendor,
Can someone let me know,
How can i extend the functionality of this module in app/design
How can i move the files from this extension to app/code, so that i can edit them there.
