Allow customer my-orders API access

Currently api only for stores, but I need to use my api on my specific order I placed on my-orders page, so that I can automate the download process. Previously the order can be accessed with a signature, but seems like the dev removed that and replaced it with magic link log in only, fully make my automation non-funtional anymore. I tried API, but there is no options for my orders.

I need this function so much
