on the wp admin bar you want users to appear automatically after entering their first name and last name. I mean, name and last name in the upper right corner. How can I do this? As you can see in the picture, this is how it comes out when I choose it. I want users to exit automatically without selecting them. I found a few sources down there, but I don't know exactly how to do it. I would be glad if you help.

[first_name] & [last_name]
