How does my toilet's outlet connect to the floor pipe without a gap?

[Jojo3739]

Hi all, first time posting here — hoping someone with experience can help me out before I start my bathroom renovation. I've just bought a toilet from Durovin Bathrooms and I'm trying to achieve a clean back-to-wall look where the cistern sits tight against the wall, like it shows in the below image

The toilet has a P-trap horizontal floor outlet and I'm confused about one specific thing:

How do I connect the pan outlet to the soil pipe in the floor without leaving an ugly gap between the back of the toilet and the wall?

Is this rear outlet or floor outlet?
