Gpay invite code

There’s an option in Jupiter app for ‘Enter Google pay Envite code’. I’ve been using app for past 3 months but today I found this!
This option is in the Settings> App Settings> Invite Code. Here’s it asks to enter our special Google pay invite code.

Kindly let me know…If anyone knows what is this option for?
