Description

Summary of changes

I've updated the from_serde and into_serde method calls according to rustwasm/wasm-bindgen#2770

use of deprecated associated function `wasm_bindgen::JsValue::into_serde`: causes dependency cycles, use `serde-wasm-bindgen` or `gloo_utils::format::JsValueSerdeExt` instead

I've chosen the gloo_utils::format::JsValueSerdeExt method as this is closest to the current implementation.
