Load-bearing wall in a house with a flat felt roof

[Hanna Eriksson Harrkvist]

Hi!
We recently bought a single-story house with a flat bitumen roof, and we want to take down a wall in the house but are unsure if the wall is load-bearing or not, though probably not. We don't have roof trusses to refer to (as far as we know) and the gutters are internal in some way.
Hence my question, does anyone here know how to assess if a wall is load-bearing?

Attached are pictures of the floor plan and a red circle around the wall we want to remove.

Best regards

Considering how the floor slab looks with three horizontal "beams," no vertical wall is likely to be load-bearing.

The doorway of 2.70 between "dining room" & "living room," does it have any "beam" in the ceiling? How thick is it?

The opening between the dining room and living room is currently a wall, this is the original plan and the wall was made by the previous owner. Now there is only the opening (an arch) between the living room and hall, and that "beam" towards the ceiling is approximately 12-13cm in width.
