reset checkbox group with action button

i have a checkbox group in my shiny dashboard body

checkboxGroupInput("dbr", selected = NULL,
                                                      h4("Select a box"),
                                                      c(
                                                          "Low" = "Low",
                                                          "Medium" = "Medium",
                                                          "High" = "High",
                                                          "Critical" = "Critical"
                                                      # End check list 
                                                      ), 
                                                      # End check group
                                                      
                                   ),

i also have an action button that I'm using as a reset button for checkbox items on the page

actionButton("reset_artifact_entry", label = "Reset")

in the server section of the code i have a call for reset

server <- function(input, output, session)

    # Rest button for artifact entry page
    observeEvent(input$reset_artifact_entry, {
        updateCheckboxGroupInput(session, "dbr", selected = NULL)
        
    })

i don't get any errors when the code runs, but nothing happens when i click the button either -
I've looked all over stackoverflow and wherever i could to find the solution to this...
I'm sure its in the way i have it set up but i can't seem to find where

cheers ~!
