AWS S3 Connector | Cannot get it to work

Hi. I am new to Wappler, but not to new to S3. The S3 bucket is set up for access and works fine in another application done in Visual Studio.

However I’m stuck at the very beginning in Wappler v5. I have added a provider to the S3 Storage and entered Service, Region, Access Key, and Secret Key. However that is where it ends. I cannot add a step to List Buckets, List Files, Upload… nothing.

I’ve tried to follow the steps for Wappler v4 but to no avail. I cannot find any examples for v5. I’m trying to evaluate if Wappler is useful for rapid development projects. But this brought evaluation to a halt

Could anyone tell me what might be wrong?
