I am preparing my presentation and I saw a template that has a black header (works like the outline) and I want to add a similar one to my project, I also want the header color to be like the color behind "My name" in the footer
Here is my project in overleaf which contains "My Project" and the one I "want its header"
Edit: I deleted overleaf link because the problem has been solved, in case you are interested you can see the code in the accepted answer
Note: I couldn't give you a specific code because I actually do not know how that kind of headers work

Use in your preamble:
UPDATE after follow-up question
Using
\documentclass[compress]{beamer}
to have the dots of the header arranged horizontally
