Default Boundary layer meshing for LES

Hello, I am new to LES turbulence modelling. I use STARCCM+. I read on the forum that for LES y+ should be smaller than 1 to capture scales in viscous sublayer. However, while using wall functions, the y+ value can be larger. I use all y+ treatments and try to obtain values around 1. I could not find any information about the meshing boundary layer while using wall functions for LES. Should I use a prism layer to obtain y+ ~1 or just refine the mesh near the wall with even cells as I understood from this research
Thank you very much in advance
