Rails 7 create camelcase output for dry::struct object

Question

I've to build a massive JSON file based on few different API calls. I want to use Dry::Struct To easily manipulate data like:

obj = Test::DataStruct.new
obj.send_envelope_description = 1

but expected output should be camelcase:

#<Test::DataStruct SendEnvelopeDescription=1>

Additionally, passed data into Test::DataStruct obj should accept camelcase keys like:

data = { SendEnvelopeDescription: 1 }
test = TestDataStruct.new(data)
 => #<Test::DataStruct SendEnvelopeDescription=1>

I tried to use transform_keys { |key| key.to_s.camelize } but I'm getting an error:

3.1.2 :045 > obj = Test::DataStruct.new(send_envelope_description: 1)

`block in resolve_missing_keys': [Test::DataStruct.new] :send_envelope_description is missing in Hash input (Dry::Struct::Error)

`block in resolve_missing_keys': :send_envelope_description is missing in Hash input (Dry::Types::MissingKeyError)

Is it possible to do so?
