open_system() not working with Model Reference

Hello,
I am using Simulink R2022b.
Currently I am trying to use the open_system() in the Command Window for a top level model that references other models using the Block "Model" from Simulink/Ports&Subsystems library.
However using :
open_system('TOP_LEVELSystem/Model (NAME_REF_MODEL)/SubsystemXYZ')
does not work because in the top level system it only identifies 'TOP_LEVELSystem/Model' as a block, but nothing below that.
Is there any workaround ? Thank you very much !

You need to get the name of the referenced model first and then open the model separately.
RefModel=get_param('TOP_LEVELSystem/Model','ModelName');
open_system(ModelName);
open_system(fullfile(ModelName,'SubsystemXYZ'))

Thank you Fangjun ! This works, had to adjust your code a little :
RefModel=get_param('TOP_LEVELSystem/Model','ModelName');
open_system(strrep(fullfile(RefModel,'SubsystemXYZ'),'\','/'));

If you want to open the model within the context of the model hierarchy, you can create a Simulink.BlockPath object and then use the open function to open the model to the location specified in the Simulink.BlockPath object.
The example on this page shows how to do this: https://www.mathworks.com/help/simulink/slref/simulink.blockpath.open.html

Thank you Sara for your reply ! Still I need to get the referenced Models name, like in Fangjuns reply.
So I cannot use :
Simulink.BlockPath = ('TopSystem/Model (RefModelName)/SubsystemXYZ')
instead I have to use:
RefModel=get_param('TOP_LEVELSystem/Model','ModelName');
bp=Simulink.BlockPath(strrep(fullfile(RefModel,'SubsystemXYZ'),'\','/'));
open(bp);
Therefore I do not see any benefit in this method. Even though in Simulink the path is displayed like this :
'TopSystem/Model (RefModelName)/SubsystemXYZ'
It does not work with the BlockPath.
