Google analytics user ID - integrated, but how I can see user id? - google-analytics

Question

I have integrated google analytics user ID, and created the view.
ga('create', 'UA-XXXXXXX-X', 'auto');
<?php if(!empty($_SESSION['user'])){ ?>
ga('set', 'userId', '<?=$_SESSION['user']['email']?>');
<?php } ?>
ga('send', 'pageview');
But in anayltics,I don't see their ID, just normal stats

The user id feature in google analytics is for use with internal calculations.
About the User ID feature
In an Analytics implementation without the User ID feature, a unique
user is counted each time your content is accessed from a different
device and at each new session. For example, a search on a phone one
day, purchase on a laptop three days later, and request for customer
service on a tablet a month after that is counted as three unique
users in a standard Analytics implementation - even if all these
actions happen with an account sign-in. While you can collect data
about each of these interactions and devices, you can’t determine if
any relationships exist. You only see independent data points.
When you implement the User ID, you can identify related actions and
devices and connect these seemingly independent data points. That same
search on a phone, purchase on a laptop, and re-engagement on a tablet
that previously looked like three unrelated actions on unrelated
devices can now be understood as three related actions on related
devices. This gives context to your analysis and so you can get a
holistic view of your users and their behaviors.
This is not something that you can see its was already used by google to calculate the data.
If you want to track your user ids you can add them as a custom dimension that you would then be able to analyze on. However there are some rules and guidelines for doing this. Universal Analytics usage guidelines
Analytics customers are prohibited from sending personal information
to Google.
The Analytics terms of service, which all Analytics customers must
adhere to, prohibits sending personally identifiable information (PII)
to Analytics (such as names, social security numbers, email addresses,
or any similar data), or data that permanently identifies a particular
device (such as a mobile phone’s unique device identifier if such an
identifier cannot be reset). Your Analytics account could be
terminated and your data destroyed if you use any of this information.
