I followed the instructions to upload a file.
https://symfony.com/bundles/ux-live-component/current/index.html#uploading-files

<div {{ attributes }}>
    <input
        data-action="change->live#action"
        data-live-action-param="files|uploadFiles"
        class="fr-upload"
        aria-describedby="upload-file-messages"
        type="file"
        id="upload-file"
        name="multiple_files[]"
        multiple
    >
</div>

    #[LiveAction]
    public function uploadFiles(
        Request $request,
    ): void {
        /** @var UploadedFile[] $allUploadedFiles */
        $allUploadedFiles = $request->files->all('multiple_files');
        if ($allUploadedFiles === []) {
            return;
        }
        
        // rest of my code
    }

And when I tried to test it, I ended up with a typing error on the files parameter.

        $component = $this->createLiveComponent(FileUpload::class, [], $this->kernelBrowser)
            ->actingAs($user)
            ->call('uploadFiles', [], ['multiple_files' => [
                new UploadedFile(...),
                new UploadedFile(...),
            ]])
            ->component()
        ;
