How do I generate a QR Code to pay to people using paynow and not on the end of receiving money?

I am thinking to prepare E-angbao for my friends who will be helping me out for my upcoming wedding. Given now that almost everyone goes cashless, I wanted to ask if there is any way to generate a specific amount tagged to 1 qr code for them to scan and direct transfer to their banks rather than having cash or me having to transfer one by one (given i will be tired after the wedding day)
