New Oak floor onto joist and concrete

Hi, can i get some help with what i do with my new oak floor.

I have engineered oak for my new room.

For the majority of the room the oak is being nailed into joisting, but there is a section where the oak comes to butt up around the older kitchen tiled area. This is concrete and level with my joists.

There is an area which will now be covered with the new oak rather than the tile. In the photo you can see this.

So this is what i was thinking:

1) Screed the concrete with a 1-2mm layer of the special self levelling compound mixed with PVA supplied. I need a flexible one as UFH in this area. This will give a nice dust free level finish.

2) Do i need to put down any membrane paper ?

3) The oak boards will float over this concrete, but do i need to glue the tongues together in this section ?

4) Do i need to glue under the board onto the concrete ? If yes no membrane would be needed i suppose.

The concrete area has been down 10 yrs and so is not new. It is fully dry.

Any help appreciated.
