Enabling hierarchical view of modules

[bongoo1]

i recently switched to vscode to check it out as a new editor for verilog.
the features added by the verilog-hdl-support extension look quite nice, but there is one thing i'm missing. maybe, i just missed something in the configuration or need to install something else in addition.

i would like to see a hierarchical view of my design, i.e. for each module, i see what other modules are instantiated within, showing a tree structure which allows me to get an overview of the design, allowing me to dive into the structure.
how can this be shown within vscode-verilog-hdl-support or what else do i need to add?

topmodule
    - submodule A
         - subsubmodule A1
         - subsubmodule A2
    - submodule B
         - subsubmodule B1
         - subsubmodule B2
    - ...
         - ....
