Single plugin upgrade

[Teejay]

Try to upgrade Skrill payment plugin for a Joomla 3.9.28 with VM3.8.8 site, installed plugin version currently is the 1.0.02, prompted to upgrade to latest version of 3.2.1, have successfully upgrade the VM AIO plugins, where all payments plugins including the VM Skrill plugins, in the tutorials on single plugin upgrade, am suppose copy the folder /admin/plugins/vmpayment/skrill into my installation, thereafter open the skrill payment method in the shop's backend and store it one time in order to update the database tables (just in case). Am bit confused here, couldn't locate this path, and do understand what it meant by copying into installation, can someone help with this upgrade?
