Reporting based on History of a property

This is very much needed, I’m relatively new HS user and started trying to build a transactional email used to communicate changes to a client based on a deal property changing. Can’t do it.
As well as access to dates, access to previous values would also be needed, so you can display the current value of a field and date it changed and the -1 value of a field (what it was changed from)
If you consider a price, you want to change a unit price for a service from say £100 per hour to £120 per hour on the 1st July 2021 you want to be able to access the current and previous value and also the date of last change.
All the data is there in the field history, we just can’t get to it.
