Rclone setup on Synology DSM

I need help because read all the documentation and sorry .... I am lost and need some help as newbie.
Here is what I want to do : Move files from a server to my NAS.
I used rclone from my pc and it works like a charm. no issue with rclone move.

Now coming to my Synology NAS: I found no instruction on how to setup rclone on DSM. Therefore I used Putty to log in my NAS and did the setup and commands, all good. Then created a scheduled task rclone move remote:shared /vol1/shared and all good.
But since a few days, for unknown reason, nothing happens. No log nothing of an issue. When I run through Putty the moving phase starts normally.
Therefore, I wuld like to setup rclone again on my NAS, maybe exploring the container method, but anything simply described would be much appreciated.

Thanks a lot.
