Hello @Ananya Sarkar ,
View designer in Azure Monitor have been transitioned to Workbooks which provide additional functionality. See Azure Monitor view designer to workbooks transition guide for details on converting your existing views to workbooks.
View designer offered the ability to generate different query-based views and visualizations. However, many high-level customizations remain limited, such as formatting the grids and tile layouts or selecting alternative graphics to represent your data.
Workbooks is a platform that unlocks the full potential of your data. workbooks not only retain all the capabilities, but also supports additional functionality through text, metrics, parameters, and much more.

Hence, you need to use Azure Firewall Workbook which provides a flexible canvas for Azure Firewall data analysis. You can use it to create rich visual reports within the Azure portal.
