Should I mention having previously received (and declined) a job offer from a potential advisor I'm inquiring into doing a master's with?

[mockturtle]

My favorite potential advisor at my top choice MS program offered me an entry-level summer technician job in 2019, which I turned down despite strong interest. I don't know if it will seem odd or insulting to mention a job offer that I ultimately declined in an introductory email, but I want to express the fact that I've been highly interested in working with this lab for several years. Is there a way to handle this politely?
