How to schedule a screenshot of dashboard at a regular interval?

[thuynh]

I am in an air-gap environment and would like to take screenshot of the dashboard at a regular interval. I prefer not to have to install additional app or python selenium.

Dashboard studio has Action -> "Download PNG"  that can be perform manually. Is there a way to use this feature and put it on a schedule or python script?

Or is there a Splunk API that can take the screenshot of a specified link?

I am currently using Splunk Enterprise 9.0.

Another thing, the screenshot should be saved on the disk instead being sent through the email.
