How to get available leve list?

[marionette-curtain]

After open leve window, how can I get available leve list? Another way to say, how can I determine my target leve is available?

Leves are a mix of support and unsupported.
There some data and functions exposed in LeveManager and your best bet to check out what exbuddy exposes https://github.com/TuckMeIntoBread/ExBuddy and LlamaLibrary https://github.com/nt153133/LlamaLibrary
