It can be reassuring to someone to know why they're being asked for certain documents during their verification.
When setting up a verification flow in the builder, you can select a template to add some context to your checks.
Once you've selected an intent you can still adjust the settings; you can toggle different document types or change the number of documents.
When starting a new verification you will see a panel that tells you what personal details will be collected during that verification.
When they get to the supporting documents step, they will see an additional message explaining the reason they're being asked to upload document(s).
