I have a helpdesk and have teams table resources. There is a many to many relationship. A Technician can have many helpdesks. I already have the resource and technicians are assigned.

HelpdeskTeamHasManyHelpDesk

    public function up()
    {
        Schema::create('help_desk_teams_has_help_desks', function (Blueprint $table) {
            $table->bigInteger('help_desk_team_id')->unsigned()->index();
            $table->foreign('help_desk_team_id')->references('id')->on('helpdesk_teams')->onDelete('cascade');
            $table->bigInteger('help_desk_id')->unsigned()->index();
            $table->foreign('help_desk_id')->references('id')->on('helpdesk')->onDelete('cascade');
            $table->timestamps();
        });

There are few technicians. I want the metric to simply count how many tasks do the technicians have.

    /**
     * Calculate the value of the metric.
     *
     * @param  \Laravel\Nova\Http\Requests\NovaRequest  $request
     * @return mixed
     */
    public function calculate(NovaRequest $request)
    {
        return $this->count($request, HelpDeskTeamHasHelpDesks::where('help_desk_team_id', HelpDeskTeam::class)->with('helpdesk'),'technician_name','help_desk_team_id')->label(function ($value) {
            return  $value . ' Technicians';
        });
    }
