+```
+
+**Example (then):**
+
+````js
+let options = { title: "Name Change" ,icon: "info", inputValue: "John Doe"};
+abp.message.prompt('Enter a new name to change your name', options)

+    }
+  });
+````

+
+### The Return Value
+
+The return value of the `abp.message.prompt(...)` function is a promise that resolves to the entered value (`string`) or `null` if the dialog is canceled/dismissed.
+
+### Parameters
+
+`abp.message.prompt(...)` function has the following parameters:
+
+* `message`: A message (`string`) to show to the user.
+* `titleOrOptionsOrCallback` (optional):
+  * a `string` title, or
+  * an `object` containing SweetAlert options (e.g., `input`, `inputAttributes`, `inputPlaceholder`), or
+  * a `function` callback that receives the resulting value (or `null`).
+* `callback` (optional): If you've passed a title as the second parameter, you can pass your callback function as the 3rd parameter.
+
+Passing a callback function is an alternative to using the returned promise.
