How can I add user_data to my events payload?

[mahdieh-dev]

Hello guys

I have a question about the custom events.

How can I add the user_data object to my custom events payload?
In the Facebook Payload Helper I can see we should send an object containing user info, like email, phone number, and other information which cannot be collected automatically. I know this payload helps with sending the data directly with the conversion API. Still, how can I send it using the react-native SDK in order to make the Conversion API dashboard receive the information and process it correctly?

I'm new to FBSDK, so if I'm making a mistake somewhere, please kindly explain it.

Thanks!
