Storing parent QuoteLine GUID in custom field when creating new QuoteLines after Quote revision

Question

I have a scenario, in Microsoft Dynamics 365 CRM: I am writing the plugin code for Quote Line, where I have a Quote that consists of multiple QuoteLine records. Whenever the Quote is revised, the system creates a new Quote along with new QuoteLine records.

Whenever a new QuoteLine is created, I need to store the GUID of the corresponding parent QuoteLine in the custom field RevisionOrigin of the newly created QuoteLine.

How can I achieve this functionality to link the new QuoteLine in the revised quote with its original parent QuoteLine?

I have used the ParentContext functionality, but it is returning the GUID of the parent QuoteId instead of the QuoteDetailId.

IPluginExecutionContext parentContext = _context.ParentContext.ParentContext; 
               
if (parentContext.InputParameters.Contains("QuoteDetailId"))
{
     Guid revisedQuoteLineId = (Guid)parentContext.InputParameters["QuoteDetailId"];
     
     entity[RevisionOrigin] = revisedQuoteLineId;
                   
     service.Update(entity);
}
