How to Programmatically Assign Attribute to All Attribute Sets in Magento 2

Magento 2 offers a flexible functionality that allows you to assign properties to each product in a catalog. Through Magento product attributes, you can configure various product features like color, size, width, height, and more.

A specific product attribute is assigned to an attribute set, which comprehensively describes all the characteristics of a product. The attribute set is utilized during the creation of every new product. To assign an attribute to the attribute set in Magento 2, navigate to the Admin Panel > Stores > Attributes > Attribute Set.

But what if you want to assign an attribute to all attribute sets? Let's say you have fifteen attribute sets, and you wish to assign your attribute to each one of them. Wouldn't it be tiresome and require excessive effort to individually assign attributes to all attribute sets from the admin panel?

Consider this scenario: you have a module that functions only when a specific attribute is assigned to all the necessary attribute sets. Would you prefer to manually assign it every time that module is installed? Of course not!

In such a situation, you can utilize the following method to programmatically assign attribute to all attribute sets in Magento 2.
