EMSDK support for chrome extension manifest version v3

We have been using emsdk to build wasm/js files to be used in a chrome extension manifest version v2.

As per guidance from Google to migrate from v2 to v3 [https://developer.chrome.com/docs/extensions/whatsnew/](url), our wasm/js files have started giving errors like -
1. wasm streaming compile failed: TypeError: Failed to fetch falling back to ArrayBuffer instantiation
2. XMLHttpRequest is not defined
at Object.readBinary
at getBinary

We have been compiling using these emsdk flags - WASM = 1, MODULARIZE =1, EXPORT_ALL = 1, EXPORT_NAME = 'library', DYNAMIC_EXECUTION=0

Is there any latest change in emsdk supporting manifest version v3 for chrome extensions?
If I am not wrong, deadline to migrate to v3 is Jan'23.

Please let us know if we should add some flags while compiling.
