Hi @Gunasekaran_Baskaran,

We have the pyExtendedAPIs navigation rule available as an extension for the addition of custom smart shapes.

Where you need to add one item and include on-click actions as the run script with the below values.

Here, We need to pass our custom utility name in the place of svfCreatePDF,

2nd script details are function name "ViewerManager.executeAction" and value is script:{name:\\u0022addNode\\u0022,type:\\u0022Utility\\u0022,args:{apiName:\\u0022pzAttachContent\\u0022}}

This will add a custom smart shape to the flow.

Regards,

K Chandra Prakash.
