@PatrickDinh i used your pr algorandfoundation/algokit-utils-ts#430 as a reference and added similar native struct support to abi crate which allowed removal of various helpers in the app client implementation, the abi handling should be more refined at this point feel free to take another look also pushed additional tests into app factory implementation as well -> #248, there is a few nested struct tests that i still need to add but ill do it after app factory pr is merged as using the factory as a fixture could simplify directly reusing existing nested struct tests from ts and py utils repos
