Feature request: Flatbuffers decoding/encoding

I often use this to experiment with protobuf for example. But I have to work with a few files seralized with flatbuffers. This is a request for implementing a feature similar to protobuf, but with flatbuffers.
I haven't had any luck finding other websites that can interactively encode/decode flatbuffers either.

The payload names no target files or tests. Start by comparing CyberChef's existing protobuf capability with the requested FlatBuffers encode/decode workflow; done means an interactive operation can handle the described FlatBuffers files in both directions.
