That looks more suitable, keep giving her more tissue just in case she wants to make an even bigger nest.
Basically at this age you shouldn't be able to see the pups at all if she has an adequate nest so that's a kind of guideline to see if she has enough.
I wouldn't remove the tray just yet, she's had enough disturbance for now so best leave it if you can.
Tempting though it is to watch her & take videos you really should be trying to leave her & the pups alone as much as possible at this stage, just do food & water but otherwise leave her in peace & quiet to raise the pups. Plenty of time to enjoy them in a couple of weeks or so!
