Change label of Interactive Grid button without creating whole new button

I am a little stuck on working with javascript in Interactive Grid in Oracle Apex. I just want to change the label of one interactive Grid save button, but I am not able to do it. I don't want to create a custom button, because then it won't detect when i mark a checkbox. I am on APEX 23.2 It shouldn't be too hard to change the label of a button right?

This code is not working

function(config) {
var $ = apex.jQuery,
toolbarData = $.apex.interactiveGrid.copyDefaultToolbar(),  // Make a copy of the default toolbar
toolbarGroup = toolbarData.toolbarRemove("actions2");       // Remove the actions2 menu group

toolbarGroup.controls.push({
    type: "BUTTON",
    label: "test",
    action: "save",
    icon: "icon-ig-save",
    iconBeforeLabel: true,
    hot: true
});

// Assign new toolbar data back to toolbarData configuration property
config.toolbarData = toolbarData;

// Return the options
return config;

}

Try this:

function(config) {
    let $ = apex.jQuery,
        toolbarData = $.apex.interactiveGrid.copyDefaultToolbar(),
        saveAction = toolbarData.toolbarFind("save");
        saveAction.label = "test";
        config.toolbarData = toolbarData;
    return config;
}
