How does Magento execute a plugin in a flow?
Magento executes plugins using these rules during each plugin execution in two main flows: Before the execution of the observed method, starting from lowest to highest sortOrder. Magento executes the current plugin’s before method. Then the current plugin’s around method is called.
How does the around method work in Magento?
