How to use the expo-permissions.CAMERA_ROLL function in expo-permissions

handleTakeImage = () => {
		Permissions.askAsync(Permissions.CAMERA_ROLL, Permissions.CAMERA)
			.then((response) => {
				const { status } = response
				if (status === 'granted') {
					ImagePicker.launchCameraAsync({
						allowsEditing: true,
						aspect: [1, 1],
						base64: true,
						quality: 0.5,
					})
						.then((response) => {
							if (!response.cancelled) {
								this.props.uploadImage(response.uri)
							}
						})
						.catch((error) => console.log(error))
				}
