I want to use the "Allow additional choices" function of the SharePoint list the selection column

[FURU]

1. In the SharePoint list, add a choice column and enable "Allow you to add choices".

2. The default SharePoint form allows users to add new choices later, in addition to the pre-registered choices.

3. When customizing a form with PowerApps, users cannot add new choices from the PowerApps combo box control.

We hope the Power Apps custom form a combo box Control to behave like SharePoint so users can add new choices！😊✨
