When you edit a dashboard, you only change the title, same goes to the lens. Let looks at dashboard JSON, the second line of the dashboard will say "label": "dashboard name", we can easily change the label, but how to change the API name?
Scenario: I create a dashboard called "backup map", by default the API name would be backup_map, this is just by replacing space with _.
After a while, I change the label from "backup map" to "my map", will the API name change from backup_map to my_map? The answer is No.
1. Use Link Widget
Create a new dashboard, add link widget and select link to Saved dashboard, and select the dashboard you would like to check.
Now, open dashboard JSON, and looks for link_1 (for this sample) widget, here we go:
"text": "Button title",
