Uploaded documents are not sent to signer

This is related to: https://docs.factorialhr.com/discuss/6194f3505e85430065f3f3a5
With the new update, we can finally upload a file to the user folder. However, it is not automatically sent to sign.

This is an example of the query:

curl -X POST 'https://api.factorialhr.com/api/v1/documents'
-H 'Authorization: Bearer '
-F 'public="true"'
-F 'file=@"/Documents/Test.pdf"'
-F 'filename="PDF2"'
-F 'request_esignature="true"'
-F 'signees="[571836]"'

Could you confirm this is a bug, and when do you estimate it will be fixed?

Thanks
