[GNC] Calculating IRR of an investment account

[Graham]

I have tried the manual without much success, and tried two different 
AIs [ChatGPT and Nova] but both give me instructions that don't seem to 
exist, such as :

 1. Click on the "Reports" menu and select "New Report".
 2. In the "Report Type" dropdown, select "Transaction".
 3. Click on the "Add Column" button to add the columns you want to
    include in your report. For example, you could add "Date",
    "Description", "Amount", and "Memo" columns.
 4. Click on the "Grouping" dropdown and select "Date".
 5. In the "Filter" section, set the date range for the period you want
    to calculate the IRR for.
 6. Click on the "Customize Report" button to open the report
    customization panel.
 7. In the "Computation" section, click on the "Add" button to add a new
    computation to your report.
 8. In the "Computation" dropdown, select "Internal Rate of Return (IRR)".

New report I take to be a new transaction report, but I can't see any 
add column button, customize report or computation options.

Am I missing something, or is AI as stupid as me? (Win 10, Gnucash 5.0)
