`requirement_modules` not available (No class 'GroupingElementPkg' in v7.0.1)

[redeexpressos]

hi. been following this page: https://dbinfrago.github.io/py-capellambse/examples/06%20Introduction%20to%20Requirement%20access%20and%20management.html
in order to work with requirements.vp addon.

I'm having some issues (which is probably related to my capella version)

import capellambse

path_to_model = "/home/re/Workspaces/capella-7.0.1.202503211540-linux-gtk-x86_64/abc/abc.aird"
model = capellambse.MelodyModel(path_to_model)
print(model)
print(model.la.all_requirements)
print(model.la.requirement_modules)

→ python3 req.py
<capellambse.model._model.MelodyModel object at 0x7a837affe450>
