Sloped screed with insulation or sloped insulation are both possible and common.
But I have yet to see how you get to those heights?
If the door has to be without sleepers and a slope of 2° is needed for 7m, I assume away from the door, then you already have a 14cm difference in height due to the slope alone. In this case there is no more room for flooring, so you have to switch to a roof with a 0° slope angle, which is certainly technically feasible without any problems, but will incur additional costs.
