Hi @colmbuckley I believe I have signed the CLA. How do we proceed?

So the environment has changed somewhat in the past few years; in particular extension manifest version 2 (MV2) is no longer compatible with Chrome OS, and MV3 is required. Eyeballing this extension, it looks as though the change might be trivial (nothing more than a slight change to manifest.js) but that would need to be tested.

Can you experiment with the change to MV3 and confirm that the extension works as expected?

See here for more details.
