how to reset moonroof sliding cover

how do i re-initialize the auto slide feature of the moonroof's sliding cover?

Haven't had to do it on the F series, but on others I've been able to reinitialize by holding the sunroof button in for a few seconds, as if to activate the venting feature. I am going by a distant memory so I could be wrong, my apologies if I've misinformed you.

i tried holding the button too as with the windows, doesnt seem to work with the moonroof
