EF Core Transaction Changes

is there a Property which indicates that there changes were made within a Transaction?

I use a Transaction inside a Razor-Component and when the user is a about to exit the Page I want to ask if he wants to apply or rollback his changes, but I only want to ask if there are changes were made.

Something like DbContext.ChangeTracker.Entries but in the context of IDbContextTransaction.

Thanks for your help!
