Whiteboard preview not working

[ancashoria]

Describe the bug
When linking a .whiteboard file from any collective, the preview are is blank. Nothing is displayed inside the preview area. This is a big problem for anyone who relies on the Whiteboard and Collectives app to create and maintain documentation.

I should mention that I have a working Whiteboard server that syncs correctly between users.

To Reproduce
Steps to reproduce the behavior:

1. Go to Files app
2. Create something.whiteboard file
3. Draw some shapes inside
4. Go to Collectives app
5. Create a collective
6. Open Smart Picker using /
7. Choose "Files"
8. Select something.whiteboard
9. The preview is not displaying the whiteboard contents

Expected behavior
The preview should display the contents of the whiteboard
