Magento 2 - How to use plugin to change product visiblity after saving product from backend?

I am new in Magento 2 and I want to change product visibility after saving product from backend using plugin.

For this I have created custom module and plugin, but I am not sure that we can achieve this using of plugin or not? Or Should I go with Observer?

I am trying something like : -

app/code/Custom/HelloWorld/etc/di.xml

<type name="MagentoCatalogModelProduct">
<plugin name="Custom-HelloWorld-product-model" type="CustomHelloWorldPluginProductPlugin" sortOrder="1" />
</type>


app/code/Custom/HelloWorld/Plugin/ProductPlugin.php

namespace CustomHelloWorldPlugin;

class ProductPlugin

public function beforeSetVisiblity(MagentoCatalogModelProduct $subject, $visiblity)

....




Please suggest. Thanks!

You should use plugin not observer, there is something need to understand that where to use plugin and where to use observers :

Use Plugins :
If you are going to change input, output ( i.e set / save data ) of some function or changing flow of request then should use plugin.

User Observer :
If you are not going to change the flow of request and intended to perform some other action on event then use Observer.
