Configuration Settings
The Configuration tab exposes all the SDK runtime parameters in a set of collapsible sections. All values are read from and written to config.json in StreamingAssets. Click Save at the bottom of the tab to apply any changes.
For a full reference of the underlying JSON structure, see Configuration File.

Saving changes
When you are done editing, click the Save button at the bottom of the tab. This writes all values back to config.json and triggers an AssetDatabase.Refresh() so Unity picks up the changes immediately.
Changes made in the Configuration Window are only persisted when you explicitly click Save. Closing the window or switching tabs without saving will discard any unsaved edits.
