In the Add External Database Collections screen:

1. Give your namespace for the collections a name
2. Enter your SPI's endpoint URL
3. Add any necessary connection data to the Configuration (ex: user name, password, secret key)

What is SPI? And what is Google sheet's SPI?

Answer 1

You should have follow the link present on SPI which could have told you it's a Service Provider Interface (SPI).
