Go on the report you created via Settings > Technical > Reports

Select your report and take the ID

You can get it when clicking on the bug and “View Metadata” also

Go on External Identifiers via Settings > Technical > External Identifiers

Search for the correct ID (in our case, invoice and group by model to be sure you take the report (ir.actions.report))

Finally replace the ID with the one of the report you created

You will therefore have your own report as default
