I've been messing around with magento 2 for some time now and especially composer. find out what all the command lines are. downloading extensions and unpacking them in the right folder also works reasonably well. now there are a number of extensions that I would like to buy from, for example: https://marketplace.magento.com/ I just really can't figure out how to install this app with composer.
For example, I entered the following command: composer require magevision/module-admin-category-product-thumbnail:v2.4.2
I need public key and private key, which I have created and filled in and entered the module name and version number. but just can't get it right. could someone explain me step by step how to install this?
I uninstalled Magento completely and reinstalled it for a fresh start. I can log in to my server with SSH and with filezilla I can access my files.
hopefully somebody can help me.
ps. i use magento 2.4.6
