text: Title: Slack Action `type_select` Not Triggering After Modal is Opened
  Body: Hello everyone, I'm seeing an issue with the SDK for a particular action `type_select`, I've provided more details below. Any help would be appreciated. Also, please let me know if more information is required from my side.
  
  ### Reproducible in:
  
  #### The `slack_bolt` version
  
  ```bash
  slack_bolt==1.20.1
  slack_sdk==3.33.1
  
  ```
  
  #### Python runtime version
  
  ```bash
  Python 3.9.6
  ```
  
  #### OS info
  
  ```bash
  ProductName:            macOS
  ProductVersion:         15.0
  BuildVersion:           24A335
  Darwin Kernel Version 24.0.0: Mon Aug 12 20:51:54 PDT 2024; root:xnu-11215.1.10~2/RELEASE_ARM64_T6000
  ```
  
  #### Steps to reproduce:
  
  (Share the commands to run, source code, and project settings (e.g., setup.py))
  
  1. Open the modal by clicking the “Create Broadcast” button.
  2. Try to select either “Task” or “FYI” from the dropdown.
  3. Observe that the modal is not dynamically updated, and no logging occurs for the type_select action.
  
  ### Expected result:
  
  I was working on a dynamic form extension in Slack using the Bolt framework. The form allows users to select between different broadcast types (such as Task or FYI) using a dropdown. Based on the selected value, additional fields should be dynamically shown in the modal. For example:
  - If the user selects Task, fields related to task details (like start date, end date, number of reminders) should appear.
  - If the user selects FYI, these fields would not be shown.
  
  Similarly, I have another dropdown for selecting the broadcast method (Channel or DM). If DM is selected, a field should appear for selecting multiple users who will receive the broadcast. However, the action for the dropdown selection `type_select` is not being triggered, preventing the dynamic form behavior from working as expected.
  
  1. The modal should open after the button is clicked.
  2. When the user selects Task or FYI in the dropdown, the type_select action should be triggered, and the modal should be updated with additional fields based on the selection.
  
  ```bash
  # In broadcast_modal_content.py
  def get_initial_blocks():
      return [
          {
              "type": "input",
              "block_id": "broadcast_type",
              "label": {"type": "plain_text", "text": "Is this a Task or FYI?"},
              "element": {
                  "type": "static_select",
                  "action_id": "type_select",  # This is the action ID not being triggered
                  "options": [
                      {"text": {"type": "plain_text", "text": "Task"}, "value": "task"},
                      {"text": {"type": "plain_text", "text": "FYI"}, "value": "fyi"}
                  ]
              }
          }
      ]
  
  # In broadcast_action.py
  @app.action("type_select")
  def update_modal_on_type_selection(ack, body, client, logger):
      ack()  # Acknowledge the action
      logger.info("type_select action triggered")  # This log is never seen
      # Further processing for modal update
  ```
  
  ### Actual result:
  
  - The open_broadcast_form action triggers correctly, and the modal opens.
  - However, the type_select action is not triggered when a selection is made in the dropdown.
