Retirement tax questions

I too would like to take advantage of the Rule of 55.  I turn 55 in 2021 but plan to separate before my 55th birthday by my choice.  I want to withdraw from my current employers 401k plan after the separation on a monthly basis until I'm 59 1/2.  Does it matter how the employer lists me from separation as I am not a "qualified retiree" in the eyes of the employer since I do not have enough years of service + age.   Am I still able to benefit and avoid the 10% penalty tax with the Rule of 55 or do I need to be a qualified retiree from my employer?
