My Mautic version is: 4.4.9  
My PHP version is: 8.0.29  
My Database type and version is: 5.7.23- |Doctrine driver|pdo\_mysql|  
This is my current workflow campaign structure in Mautic which is executed based on when a contact utm field will contain “Home” and lead stage should be “Lead” then this workflow will trigger E.g I just run the workflow according to utc time 11 am right now(Wednesday)

Hi,  
Greetings of the day,  
Could someone please explain how a plugin bundle works, including the flow of data within the bundle, i.e., the process of transferring data from one file to another?  
Thanks for your Consideration,  
Pranay.
