Installation of dolfinx latest version with conda

Hello, I would like to install fenicsx on a conda environment with python 3.7 (I need this version because I also need to install a package that won’t support further versions of python).

The problem is that, for the moment, I need in my script to use gmshio, but the installation with conda provides me with dolfinx 0.4 which does not have it. I need gmshio to read a mesh from mesh file via the function read_from_msh, and also get the cell and facet markers via this function.

So here is my question, how can I install dolfinx latest version (or at least one with gmshio), or how can I load a msh file and cell & facets without using gmshio.read_from_msh.

Thanks and regards.
