Do i need to get L2 visa stamp to be able to apply for EAD if my COS from F2 to L2 is approved?

My Husband’s petition for change of status from OPT (F1) to L1A is approved. My COS from F2 to L2 is also approved. But I dont have an L2 stamp yet. I want to start working and need to apply for my EAD. Do i first need to get an L2 stamp to be able to apply for EAD?
