debusine provide-signature for sponsored uploads

I triggered a workflow for a sponsored package (https://debusine.debian.net/debian/developers/work-request/89629/), so I needed to provide my openpgp key id when providing the signature. According to the debusine command help, its usage is usage: debusine provide-signature [-h] work_request_id [extra_args ...], being extra_args Additional arguments passed to debsign.

So I tried with debusine provide-signature 89629 -k7E9474EAEE69093B207AB76527DE3D45104886EF, but I got debusine: error: unrecognized arguments: -k7E9474EAEE69093B207AB76527DE3D45104886EF.

I admit this is a lazy question: could you please clarify how extra_args should be passed to debusine provide-signature?
