Should I let my mother in law in the room for the delivery

My MIL and I are close in general but not close with personal things. This is my third delivery and she hasn’t been in the room either time. I plan on going completely natural(only reason I thought about letting her be in the room) and I don’t feel like my husband will be enough support lol it’s always been just my husband and step dad(long story short I don’t talk to my mom and they’re no longer married)

I’m not sure if I feel completely comfortable with her in the room or not but I wanna go completely natural so bad since this is my last baby and need support to help me get through it
