How to import a .msh file (2D) in Matlab ?

I used GMSH to build a mesh with a simple 2D geometry. So I got an .msh file that I want to read on Matlab to get the (p,e,t) matrices from the pdetoolbox. I have attached the .zip folder containing the .msh file.

I found a script on gmsh2pdetoolbox which is used to read .msh files on Matlab to obtain the 3 matrices (p,e,t) . When trying to run it, the following error is displayed:

Syntax error (no $Nodes/$NOD) in: mesh_PB.msh
Syntax error (no $Elements/$ELM) in: mesh_PB.msh
Dot indexing is not supported for variables of this type.

Error in gmsh2pdetoolbox_rev>load_gmsh4 (line 275)
for i = 1:msh.nbElm
    
    Error in gmsh2pdetoolbox_rev (line 18)
    mesh_structure = load_gmsh4(filename,-1);
    
    Error in Script_A_MH_L (line 34)
    [p,e,t] = gmsh2pdetoolbox_rev('mesh_PB.msh');

The command used for the execution is :

    [p,e,t] = gmsh2pdetoolbox_rev('mesh_PB.msh'); 

As I understand it, the msh structure does not contain an element called nbElm. Either there is an error in the script I found or there is a detail I am missing.
