transparent text on button with LinearGradient react antive

I am making an app and I am using a button and I want this button to have a transparent color so it gets the color behind of it from a LinearGradient.

what I have is this:

<LinearGradient
        colors={["#411a50", "#bb265f"]}
        start={{ x: 0.1, y: 0.5 }}
        end={{ x: 0.65, y: 0.65 }}
        locations={[0.5, 0.5]}
        style={styles.box}
      >
        <Text style={styles.titleText}>OasysNOW</Text>
        <Text style={styles.bodyText}>
          Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do
          eiusmod tempor incididunt ut labore et dolore magna aliqua. Nec
          tincidunt praesent semper feugiat nibh sed pulvinar proin. Suspendisse
          ultrices gravida dictum fusce. Quisque id diam vel quam. Consequat
          interdum varius sit amet mattis vulputate enim nulla. Tincidunt
          praesent semper feugiat nibh sed pulvina
        </Text>
        <TouchableOpacity style={styles.buttonStyle}>
          <Text style={[styles.buttonText, { color: "#411a50" }]}>
            LET'S GET <Text style={styles.buttonText}>STARTED</Text>
          </Text>
        </TouchableOpacity>
      </LinearGradient>

this becomes like this:

and also:

container: {
     flex: 1,
        justifyContent: "center",
        alignItems: "center",
      },
      box: {
        width: "100%",
        height: "100%",
      },
      buttonStyle: {
        backgroundColor: "#fff",
        padding: 10,
        marginTop: 20,
        marginLeft: 95,
        marginRight: 95,
        justifyContent: "center",
        borderRadius: 10,
      },
      buttonText: {
        color: "#bb265f",
        textAlign: "center",
        fontSize: 20,
      },
      titleText: {
        fontSize: 20,
        fontWeight: "bold",
        textAlign: "center",
        color: "#fff",
      },
      bodyText: {
        color: "#fff",
        fontSize: 16,
        textAlign: "justify",
        paddingVertical: 20,
        paddingHorizontal: 20,
      },

I want to have the button to be like this:
