Update Litmos Assessment Settings

I need a script that logs in, and for each course, navigate to the Settings tab of the Assessment for that course and change the settings according to the settings provided in the input file. See attachment. Ignore courses that have no assessment. It's a simpler version of what you have already written. Here's a video to help: https://recordit.co/NiHx3UaVjN

Sample input file also attached. It contains 4 records:
1. Set only the Passmark (this is the most likely scenario); leave every other field alone.
2. Set all fields
3. Set only Description and Passmark
4. Select some fields not others

If a field is EMPTY, that means DO NOTHING
If a checkbox field is set to "checked" then check it; if "unchecked" then uncheck it; if EMPTY, do nothing to it

I hope that's clear. Let me know if you have any questions.
