I try to override the following template which is under www.example.net/newsletter/manage with my own
/vendor/magento/module-customer/view/frontend/templates/form/newsletter.phtml
Block class: Magento\Customer\Block\Newsletter
I already asked the question Override template and block from a module?, and I understood it. But I struggle to find out, how to override this one.
I added my custom template file newsletter.phtml
to my module:
app\code\Black\Newsletter2Go\view\frontend\templates\form\newsletter.phtml
What step is required next? I guess I need to add a layout file too, but how do I know how it has to be named?
I need a walkthrough for this one please so that I can understand how this all works together.
