QR Generator with additional field

I'm using to Generate QRVisa to generate QRCode. But I only see document mention to use subtag no.9  in tag no.62 to set enable address, email, phone. However, I saw this description "Additional information may be populated either by the merchant/acquirer, or the consumer may be prompted for entry on the app."

So What can I use a parameter to set value for email, phone, or address by the merchant?
