Hmmm... probably you have tested it ... For me it seems here is clear

https://docs.celonis.com/en/aws-s3.html

Once you have finished the setup in AWS, go to the AF, select the module AWS S3 (the function you want, I picked Get File) then press in Add to define the connection and you get another pop-up where to write the Key and Secret

But, you know, I haven't yet tested it in real-life end-to-end, so it is perfectly possible I am wrong.

Hi Gost,

It seems that the specific action is not possible unless there is access to the paid account (I was using the free plan).

Sorry, but at least you got the reason... you can't fix it, but you know why it doesn't work ... 😛

That is true 😅
