When installing firebolt-cli via pip install under python 3.9, every command returns a trio deprecation message in stderr like this:

firebolt engine start --wait my_engine
/Users/name/Library/Python/3.9/lib/python/site-packages/anyio/_backends/_trio.py:164: TrioDeprecationWarning: trio.MultiError is deprecated since Trio 0.22.0; use BaseExceptionGroup (on Python 3.11 and later) or exceptiongroup.BaseExceptionGroup (earlier versions) instead (https://github.com/python-trio/trio/issues/2211)
  class ExceptionGroup(BaseExceptionGroup, trio.MultiError):
