Correct dataset for AGL sounds?

It took me a while figure out how to fix this, so I'm writing down a complete response in case this is useful to someone in the future.

Here's the solution:

metadata/datasets.yaml has a "key" field, which for this dataset was 1sbeoPlEKxyjzlmWgzeSCVrumoS0wlMpX_Puv074r9lM which is wrong, so we'll look up information to replace that
Visit the REAL spreadsheet you want to link up. In may case, it's https://docs.google.com/spreadsheets/d/1yCKAsu-vvQGemPga22F1cdtn90gs7Vp8UCto7HH10cE/edit#gid=818895612
From that address, remove the stuff at the beginning up to the d/, and everything following the next /. This leads to 1yCKAsu-vvQGemPga22F1cdtn90gs7Vp8UCto7HH10cE
Copy-paste the resulting text into metadata/datasets.yaml next to the appropriate key field
Commit

Things not to do:

I saw scripts/cache_datasets.R combines this key field with the fixed text, like this: https://docs.google.com/spreadsheets/d/*$KEY*/export?id=*$KEY*&format=csv (NB key repeated)
I got lost for a while, because if one composes such an address my hand, and pastes it on a browser, one gets a 400 error. Not sure why this fails when I do it, but not when metalab does it, but whatever.
Don't look up the link to the csv for that spreadsheet that you want to link up. For instance, for my case, it was https://docs.google.com/spreadsheets/d/e/2PACX-1vQZFwVnJ7R-H-GSGYBeyeDM6LnakZN03efo6OCcGO7bLmaN8VviSurR0v5g2CbxaLYgOCXGAudt1k8P/pub?gid=1664900378&single=true&output=csv -- notice that neither the fixed text used by cache_datasets nor the key are found in the latter address
