Unable to find .bidsignore and dataset.description files when trying to upload them on OpenNeuro

I have a Windows11 laptop. After clicking “upload” on OpenNeuro, a window page popped up and asked me to select the folder. However, I was not able to find .bidsignore nor dataset.description files when browsing the folder on that window page. I am able to find and view those files on my local desktop. I tried (1) upload the dataset from Box Drive, (2) use a MacBook, and (3) different search engines (i.e., Google, Microsoft Edge, and Firefox) but the same things happened. Any thoughts would be really helpful and appreciated!
