Unable to access event to stop propagation

[minedun6]

I have a clickable row which contains a menu with the command as presented in the screenshot below.

The problem is that I'm trying to stop the command event from bubbeling up to the row.
But I can't seem to find any documentation which can help with the following.
Can I get some help please :)

Have a nice day !

you can stop propagation on onMouseDown event.

onMouseDown={e => {
  e.preventDefault()
  e.stopPropagation()
}}
