How to change the value of the "alternativeText" property of an image after having uploaded it to the route /upload API?

Hello community!
I’ve gone through the docs without any answer to my problem.
I download an image that is on a bucket and I want to upload it to Strapi via the /upload API.
No problem, it works except that the “alternativeText” property is empty. I want to fill this value.
Following the POST response from the image upload, I got the image ID.
Now I want to update the “alternativeText” property by making a POST request on the route /upload?id=imageId with a payload but it does not work.
I do it in Python.
How do you do it on your side please?

        files = {
                   'path/files' , 

        headers = {
            "accept" : "application/json",
            "Authorization" : 'Bearer my_token' ,
            url= 'http://localhost:1337/api/upload',

        content = json.loads(responseUploadImage.content)
        imageID= content[0]['id']

        payload= json.dumps({
            'fileInfo': {"alternativeText":"alt","caption":"caption","name":"iamage_name"}

            url=  'http://localhost:1337/api/upload?id=' + str(imageID),
            headers = {
                "accept" : "application/json",
                "Authorization" : 'Bearer ' + os.environ['API_KEY'],
