cannot able to share an image with text using Navigator.share

I want to share an image with caption. here I have a code which generate an image dynamically with using html-to-image plugin. Everything works properly but the text get discarded while the image get share on Whatsapp, Facebook and etc.

And on the otherside if i pass two file as an image and try to share then text get included on both the image.

following is my code

getScoreImage() {
    this.dynamicImageEle = document.getElementById('quiz-share-image-wrap');

    const v_this = this;

        htmlToImage.toPng(this.dynamicImageEle)
        .then(function (dataUrl) {
        var img = new Image();
        img.src = dataUrl;
        v_this.dynamicImageBase64 = img.src;
        const file = v_this.dataURLtoFile(dataUrl, "ipl-quiz.png");

        setTimeout(()=> {
            v_this.shareFile(file);
        },100)
    })
    .catch(function (error) {
        console.error('oops, something went wrong!', error);
    });
}

dataURLtoFile(dataurl: any, filename:any) {
    var arr = dataurl.split(","),
        mimeType = arr[0].match(/:(.*?);/)[1],
        decodedData = atob(arr[1]),
        lengthOfDecodedData = decodedData.length,
        u8array = new Uint8Array(lengthOfDecodedData);
    while (lengthOfDecodedData--) {
        u8array[lengthOfDecodedData] = decodedData.charCodeAt(lengthOfDecodedData);
    }
    return new File([u8array], filename, { type: mimeType });
    
};

async shareFile(file:any) {
    if (navigator.canShare && navigator.canShare({ files: [file] })) {
        await navigator.share({
            "title": this.shareTitle,
            "text": this.shareText,
            "files": [file, file],
        })
        .then(() => console.log("Share was successful."))
        .catch((error) => console.log("Sharing failed", error));
    } else {
        console.log(`Your system doesn't support sharing files.`);
    }
};

Current Output with image and no text

If Pass two image then output is proper but 2 image is not expected

Expecting output I want to share is image with text.
