[Gmsh] surface mesh coarsening

Dear all,

Can someone explain me how to use gmesh to coarsen a closed surface mesh? I attach a simple geometry as test data.
I tried in vain in the GUI to put ‘options > mesh > element size’ to a value bigger than one.
The data I want to apply it to is a heart geometry which has originally 10^6 vertices and 5 10^5 faces, which should be reduced to approx. 500 faces.

Thank you very much for your assistance.
