In the next step, you'll be prompted to enter your Google Analytics 4 Measurement ID (also known as a "G-" ID), which you will be able to find in your Google Analytics Data Streams. It will look something like G-XXXXXXXXXX.

❗️In most cases, a single web data stream will meet your measurement needs.
