Open S3 Sign Download in Browser

Just wondering if there was anyway to set for S3 signed url downloads to open in the browser by default, rather than download (regardless of browser settings).

There are a few suggested options here:

I’ve tried amending the server put file action as the post suggests, but the files on Digital Ocean always end up as application/octet-stream, if the SO post is right this may be why they download by default?

I’m accessing the files from a button in a table row to trigger a ‘download’ server action, sending the key with thi srequest. On success this runs a ‘browser go to’ to the S3 signed download url. This is working fine and on chrome I get the option to save or open depending on browser settings. I’d like to run the same actions but just default to opening with no option if possible.
