Thank you for your post!
I understand that you're trying to edit the description within your Microsoft Sentinel workbook and to hopefully help point you in the right direction, I'll share my findings below.
Findings:
When it comes to editing the Workbook description from the MS Sentinel workbook page, I wasn't able to find a way to do this within Sentinel or the Workbook resource itself.
However, you should be able to update the name of your workbook and add informational text to help guide users and provide details regarding the data contained in the workbook.
Additional Links:
- Visualize and monitor your data by using workbooks in Microsoft Sentinel
- Azure Sentinel Workbooks 101 (with sample Workbook)
I hope this helps!
