Set the HelperText attribute dynamically

Is it possible to dynamically change the HelperText of another field when changing the selected option of a Radiobutton? Not sure if I need to do this from the Radiobutton, or fetch the value from the field I want to adjust?

Radio::make('job_salary_type')
                                            ->columnSpanFull()
                                            ->inline()
                                            ->reactive()
                                            ->label(__('strings.fields.job_salary_type'))
                                            ->options([
                                                '1' => __('strings.strings.monthly'),
                                                '2' => __('strings.strings.yearly'),
                                            ])
                                            ->required()
                                            ->afterStateUpdated(function (Closure $set, $get, $state) {
                                                
                                                // If the selected option is 1 then change the helperText to monthly
                                                // If the selected option is 2 then change the helperText to yearly
                                                $helperText = __('strings.strings.average_salary', ['type' => __('strings.strings.yearly')]);
 
                                                // Set the helperText of the 'job_salary_avg' field
                                                // But how?
                                                $set('job_salary_avg', $helperText);
                                            }),
