Create a new row in Airtable when user signs up.

I would like to create a new row for each user in my airtable database when the user signs up.  Right now I have the sign up working and attempted to add the api call using user.email and user.id.  I'll include my figma setup and my API setup here.  How should I rework this so that the row is successfully made?

Here's my button component:
Button/Primary [action:remote] [action:login:firebase-email-password]

Here's my API call.

POST url: https://api.airtable.com/v0/*********/userCollections

{
  "records": [
    "fields": {
      "Name": "${user.email}",
      "palette": "",
      "user": "${user.id}"
    }
  ]
}

I don't have any query parameters because I assume user.email and user.id are supposed to auto-populate?  This all works when I have hardcoded field values but now that I am using ${user.email} and ${user.id} I can't get the test API call to work and it doesn't work from Bravo Vision.

I read in the docs that user.id and user.email should be auto-populated when the user signs in?

If I try to switch the action tags around on the button I am not able to set up an API call.  I thought this might help since they will need to sign in first before the app can grab their user.id and user.email
