Struggeling to make a simple thing-please help

Hello everyone,
I am new here,discovering jetadmin. I am trying to make a simple thing but can’t make it work:
I have to collections in my firestore:

and users…
In my admin ,I have a table for messages:

When I click on the user field, i want to link to an other page and pass the user id parameter (in order to filter on my users page).

So on my field user, I add an action like this:

but when I try it, the parameter sent is not only the user id and looks like this:


How can I do to open the users page with the good user id as parameter and not this long url??

Thanks by advance :hugs:

PS:I wanted to put images to explain but as a new user I can’t put many images (which is really stupid…)
