Mesh refinement in GMSH based on specific points

I am working with GMSH to do stepwise mesh refinement. In each step I am generating a point cloud where I want to refine the mesh in the vicinity of each point. Is there a way to do a refinement based on how many points are in each area (as some sort of distance function)?

I am working with 2D meshes in planar structures and am importing the returned mesh in Matlab.

I am trying to achieve something with a distance Field and an overlaying Threshhold Field, but here I need to define the Meshsize in the vicinity of the points, it does not let me control the mesh based on how many points are in the area.

here in the center the mesh should be denser than around

Field[1] = Distance;
Field[1].PointsList = {7,8,9,10,11,12,13,14,15,16,17};

Field[2] = Threshold;
Field[2].InField = 1;
Field[2].SizeMin = lc/4;
Field[2].SizeMax = lc;
Field[2].DistMin = lambda/200;
Field[2].DistMax = lambda/100;

Field[7] = Min;
Field[7].FieldsList = {2,3};
Background Field = 7;
