Letters Loading Web

Good afternoon, thank you very much in advance.
My page is the NEXT: https://www.egr-studio.com (TEMA: SYDNEY)

I would add a few letters to open the web (such as clock “loading”) looks like the following web: https://www.eginstill.com/

The letters with white background EGINSTILL leaving the open web.

You know how I can do?

Thank you!
Best regards,

EDGAR
