Scores to Assignments to LTI

[IanGoh]

Now that I have my hands on scores, I'm trying to track back to if a certain score was associated with an LTI tool.

From scores I can get to assignments.

And, then it seems assignments ->  lti_line_items -> lti_resource_links -> context_external_tools -> developer_key

I was wondering if there was a quicker way, e.g., assignments has lti_context_id.  Is that useful anywhere?

Thanks in advance

Checking one more time, is  lti_context_id useful anywhere?
