Download XML attachments in QAComplete

Hello all

In QAC On-Prem, we want to add an XML attachment to a TestCase and then download them again later. Currently we get the following error message, when we try to download the attachment:

{"errors":[{"message":"'Xml' Features have been disabled by your administrator","code":403}]}

Currently we use the following workaround.
1. click on the file icon
2. select "save link as

Is there a setting in QAComplete to allow the download of XML files?

Many thanks
Jens
