  const ClickHandler =()=>{
        //pass data to Test2
      
  }

I think there will be two methods to do this.

  1. Be a child of the same parent and share props.
  import {useState} from "React"
   
  const TestOneComponent = ({value}) => (
    <span>{value.toString()}<span>
  )

  const TestTwoComponent = ({value, onClick}) => (
    <span>{value.toString()}</span>
    <button onClick={onClick}>Increase Value</button>
  )

  const ParentComponent = () => {
    const [value, setValue] = useState(0)

    const onClick = () => {
      setValue(value + 1)
    }

    return (
      <>
        <TestOneComponent value={value}>
        <TestTwoComponent value={value} onClick={onClick}>
      </>
    )
  }
  1. Manage store and pass props to those two components.

Either you can use props to pass data in to the other component and render it when the onClick event is triggered or

you can navigate to a new page by onClick event and pass data into the header/route and access that data in the new page's component
