4 hours ago @yarikoptic -- thanks for filing this -- just tagging some working code we have for calling any operation upon button click in the FileBrowser here (this is from the LINC side when we want to issue CloudFront cookies prior to proceeding to neuroglancer)
I'm assuming this this nwb use case you'd also want to ping an endpoint rather than including a potentially minted presigned URL in every asset.metadata upfront -- see code reference here and here
Happy to share additional unsolicited advice 😉 -- (e.g. make sure to leverage aioboto3 here instead of boto3 -- boto is blocking for expensive presigned url construction!)

Inspired by @aaronkanzer pointer to docs on how integration is happening for zarrs in LINC in
but I guess in many cases for simple .nwb we would be fine if we just point to "minted on demand" (the
/download/end point at the time of external service might already be lacking session/context to authenticate seems since https://neurosift.app/?p=/nwb&url=https://api.dandiarchive.org/api/assets/dd8e4fed-743b-497e-b4da-db0ba71ff5d8/download/&dandisetId=001169&dandisetVersion=draft does not work for me even though I can download that asset in the same browser... attn @magland ) Thus we would just annotate which services in general would have ability to access embargoed assets, and trigger minting URLs upon click instead of providing ready to use URLs.
