Help coming out as aroace?

Hi everyone!! I'm Lucy and I came out as pansexual to my mom in 2023, to which both my mom and dad supported me, buying me a flag and my mom making me a little craft with the colors of the flag on it. My parents are supportive of the lgbtq+ community, but recently I have been thinking and realized I was aroace too. I'm scared to come out as aroace to them even though they will most likely be supportive of me, but I'm still a bit scared. Any tips?
