+    Multiple (module) buttons
+    -------------------------
+
+    By default, Shiny will listen for the default `id` being used and call
+    `session.bookmark()` on button click. However, this will not work if the bookmark
+    button is used within a module or more than one bookmark button is being utilized.
+
+    For both situations, a custom `id` value is required.
+
+    There are two recommendations to maintain the expected bookmark behavior:
+    * The supplied `id` value should be excluded from bookmarking with
+      `session.bookmark.exclude.append(ID)`.
+    * A reactive effect should be added that performs the bookmarking
+      (`session.bookmark()`) when the button is pressed.
+
+    ```python
+    session.bookmark.exclude.append("CUSTOM_ID")
+
+    @reactive.effect
+    @reactive.event(input.CUSTOM_ID)
+    async def _():
+        await session.bookmark()
+    ```
