+### Screenshot Button
+
+You can show a button that allows the user to take a screenshot in the Feedback Widget. The button is shown when `enableTakeScreenshot` is set to `true` in the `feedbackIntegration` method like in the example below.
+
+```javascript
+import * as Sentry from "@sentry/react-native";
+
+Sentry.feedbackIntegration({
+  enableTakeScreenshot: true,
+  screenshotButtonOptions: {
+    styles: {
+      triggerButton: {
+        marginBottom: 75,
+      },
+    },
+  },
+})
+
+Sentry.showFeedbackButton();
+```
+
+You can customize the Feedback Widget screenshot button text with the following options.
+
+| Key                | Default             | Description                               |
+| ------------------ | ------------------- | ----------------------------------------- |
+| `triggerLabel`     | `"Take Screenshot"` | The label for the Screenshot button.      |
+| `triggerAriaLabel` | -                   | The aria label for the Screenshot button. |
+
+The capture screenshot button can be customized too. The following styles are available.
+
+| Style           | Type         | Description                       |
+| --------------- | ------------ | --------------------------------- |
+| `triggerButton` | `ViewStyle`  | The screenshot button style.      |
+| `triggerText`   | `TextStyle`  | The screenshot button text style. |
+| `triggerIcon`   | `ImageStyle` | The screenshot button icon style. |
