CAN H4Ead be filed with post 6th year H1B extension pending?

My employer has filed for a post 6th year H1b extension based on my perm being filed 365 days prior to my max out date.
My I140 is being filed as well in premium. Can i apply for H4 ead with my H1b extension receipt notice once my i140 gets approved?

You can apply for H4 EAD with approved i140.
