Issue Summary

The number of spaces visible in the JSM Project Knowledge Base linked on-prem Confluence site is limited to 50. 

Steps to Reproduce

1. Create an app tunnel and app link between the cloud JSM and On-prem Confluence using this link. 
2. Go to JSM project > Project Settings > Knowledge Base, and then click on link space. 
3. In the drop down only 50 spaces are visible. 

Expected Results

We should be able to see all the spaces assuming there are more than 50 spaces. 

Actual Results

Up to 50 results are visible. 

Workaround

Currently, there is no known workaround for this behaviour. A workaround will be added here when available
