Get current user’s email via API

Hello guys, I’m struggling since hours with these 2 codes:

document.tidioIdentify = {
  distinct_id: "unique_id", // Unique user ID in your system
  email: "contact_mail", // User email
  name: "John Doe", // Visitor name
  city: "Denver", // City
  country: "US" // Country
};

tidioChatApi.setVisitorData({
  email: "[email protected]",
  tags: ["tag1", "tag2"]
});

The documentation doesn’t explain anything about how to use it in WordPress. I googled everywhere and couldn’t find a solution.

How can I get the current user’s email address (logged in) into my Tidio chat?

Thanks for your help!
Daniel
