Make a Google Cloud signed url public - google-cloud-platform

Question

I have been trying to search through the documentations and I think I found a solution but it isn't working and I continue to get an error. What I am doing for a signedUrl is
const [url] = await googleCloud
.bucket(bucketName)
.file(filename)
.makePublic()
.getSignedUrl(options);
return { url };
What I added from what I found in the docs was makePublic() but this throws and error as it is followed by getSignedUrl. I don't have any problem if I remove makePublic() and upload the file from the signed url but the file won't be public.
Any advice on how I should proceed?
UPDATE
The error I am seeing when trying to get a signed url with makePublic is [Unhandled promise rejection: Error: googleCloud.bucket(...).file(...).makePublic(...).getSignedUrl is not a function].
Additional information in regards to the options being send with getSignedUrl function are
const options = {
version: 'v4',
action: 'write',
expires: Date.now() + 15 * 60 * 1000, // 15 minutes
contentType: 'video/quicktime',
};
UPDATE (How frontend handles signed url)
const submitReview = async () => {
const url = await getSignedUrl({
variables: { filename: "google3.mov" }
}).then(async response => {
if (response.data && response.data.getSignedUrl) {
const url = response.data.getSignedUrl.url;
const pathUrl = url.split('?');
const videoPath = pathUrl[0];
const uploadedReponse = await uploadToGoogleCloud(url);
}
});
}
const uploadToGoogleCloud = async (url) => {
const videoFile = await fetch(video.uri);
const blob = await videoFile.blob();
const response = await fetch(url, {
method: 'PUT',
body: blob
}).then(res => console.log("thres is ", res)).catch(e => console.log(e));
}
