Bryan Adams tickets pickup at venue

I bought Gold tickets for Bryan Adams' show from the Zomato site, not app. Got a WhatsApp MSG linked to the Zomato app. Which informed me that I have to pick up the paper tickets at Bambolim stadium on the day of the concert. No QR code, no home delivery of tickets. Anyone has any idea what time do I need to go to pick up the tix? How bad is the line going to be? Infuriating that they didn't mention this while taking my money.
