What is the type of trigger?

[alamenai]

I have a function called getData that runs a trigger in SWRMutation. This function is inside the component however, I want to make it independent by passing the trigger inside but I could not figure out the type of trigger:

 const getData = () => {
    let formattedData: unknown
    let formattedChartData: unknown

    if (trigger) {
      trigger().then((data) => {
        if (data) {
          formattedData = data.formattedData
          formattedChartData = data.formattedChartDa
        }
      })
    }

    return {
      data: formattedData as FinancialAnalysisAPIResponse,
      timeSeries: formattedChartData as ChartTimeSerie[],
    }
  }
 

I want it like this :

export const getData ( trigger: WHAT IS THE TYPE ?) {

// rest of the code

}
```ts
