@mehavel Can you provide more detail on why the msal service should be marked as optional?

[mehavel]

@jasonnutter we are planning to load a module, without authentication. the other modules will be disabled for the first time. During the next load all the modules will be enabled and will be behind msal. The is based on a feature flag. We tried injecting msalservice as optional for the first time and it did not work. hope this helps

@mehavel Makes sense, thanks for the explanation.
