What happens to Citrix Workspace app support after you leave Citrix

It looks like we aren't renewing our Citrix licence. We will continue Citrix hosted by someone else to access a few of our LoB applications.

If we have issues for example cursors disappearing in XenApp apps accessed from our Amazon Workspaces environment do we have to go through the vendor's support desk and they contact Citrix support on our behalf?
