I need a more complete behavior package API

First of all, this doesn't seem to be a bug. I just want to make suggestions, but I can't find a suitable place. There are many functions of the add-on package that can't be implemented. For example, the UI of the custom box can't be done by a machine, and the script can't be run in the bedrock version. Only the initiator can be used. I hope that it can be supported in the future as soon as possible, and the API can be improved as soon as possible, so that the behavior package can Realize more functions
