ibflex.client.download only appears to work after I manually log-in to IBKR account

[cppt]

Attempting to retrive a flex query for my IBKR account and when I run the below, I'm initially met with timeout errors seemingly due to lack of IBKR rresponse:

response = client.download(FLEX_TOKEN, QUERY_ID) 

> StatementGenerationTimeout                Traceback (most recent call last)

In attempting to debug the last couple times, I've logged in to my account via web to check token, query id, etc, after which running the same now returns the query results. Is this an expected/needed step to take to use the client download method(s) or is there some other reason it appears to work this way?
