Hello Team,

Is there a way to add an extra field in workflow inbox complete step ? See attached figure.

I would like to add a textarea under comments..something like sample text.

Thanks

This is not a recommended use case - modifying Workflow behavior and dialogs is not a supported use case for extending Workflow functionality --  as described here :
