how to change accent color to gradient

[timi-codes]

I would like to know how to change the accent color to a gradient. I have tried set the accent color as const accentColor='linear-gradient(to right, #91CB3E, #02C39A)'

  <Tour
      onAfterOpen={disableBody}
      onBeforeClose={enableBody}
      // onRequestClose={() => }
      steps={tourConfig}
      isOpen
      className="helper"
      rounded={5}
      accentColor={accentColor}
    />
