Further development of UXP photoshop API

I feel that API is lacking a lot in photoshop, typically: I tried to load action in photoshop, because I am doing UXP batch processing, in addition to the feature we have made, I want to let users create their own action and then add it to the plugin and then press run in batch, I tried many ways but in UXP it seems not to allow access, on CEP JSX platform it has allowed that, it is really convenient
