add verts and tris to interactive cloth

how can i increase the amount of verts and tris in an interactive cloth?

when i look under “inspector → interactive cloth → mesh”, the plane only has 121 verts and 200 tris and i want to increase that.
do I create a new mesh? if so how could i do that?

thanks in advance

solved problem myself!!
i made a plane model with more verts and tris in Blender. saved it in the Unity assets folder (unity automatically imported the model).
then i was able to use the mesh of the model made in blender to the interactive cloth!!
