I am trying to implement an feature with read a large data file in Blazor Webassambly

public async Task OnInputFileChange_org(InputFileChangeEventArgs e)
{

     var singleFile = e.File;
    long maxFileSize = 1024L * 1024L * 1024L * 2L;
    var stream = singleFile.OpenReadStream(maxFileSize);
    var fileBuffer = new byte[stream.Length];
    var res = readData(fileBuffer)
}

I always get error:
Supplied file with size 8113469 bytes exceeds the maximum of 15360 bytes.

Is this the limit in Blazor Webassambly? Or how can I solve this problem?

Thanks for the help.
