Help with bringing variables to dashboard for Blinking example

Hi all I new to node-red and I trying to toggle the output on my rpi.

I found the dsm node and the Blinking example which does everything I want, and here's the but, I'd like to bring the the variables to the dashboard so the user can change the "on_time" and off_time". I'm not sure how to do this or if it's possible, any help would be appreciate. Tks

"data": {
"on": 1,
"off": 0,
"on_time": 1000,
"off_time": 1000,
"blinks": 3,
"count": 0
},
