Objects on a string following each other

Hi Everyone :slight_smile:

I have two objects and I would like to connect them with a softbody string in such a way that the first object will pull the other one when animated. It should be simple but I cannot come up with a good way to do it. I would like the string to be rigid enough so the movement can be transferred to the other object. I’m guessing I need to use a hook modifier and some sort of constraint but nothing I did so far seems to work.

Thank you for your help!
