For more information on how to configure the plugin element and details about each field, please refer to the plugin documentation at https://docs.zeroqode.com/plugins/wasabi-cloud-storage#plugin-fields-events-actions-and-states.
Now you have an uploader on the page, which you can use to upload files into the plugin element. In this case the plugin element keeps your file. To be able to upload the file directly into Wasabi account (in your bucket-> folder) you need to trigger the plugin action – Upload WasabiS3 A. To do so, click the Uploader, select the file from your PC in the open window, then click the Upload button to trigger the plugin action.
All these actions will upload the file from the Bubble app into the Wasabi account using the plugin.For example, if you click Uploader, select the file from your PC in the opened window, then click the Upload button, it triggers the plugin action. All these actions will upload the file from the Bubble app into the Wasabi account using the plugin.
