3. Press Authorize button

Expected results: Authorization is successful
Actual results: Nothing happens, authorization message not outputted in the Console

Reproducible with: Localization 0.11.0-preview - 1.0.0-pre.9 (2021.2.0a18)
Not reproducible with: Localization 0.7.1-preview - 1.0.0-pre.9 (2019.4.27f1, 2020.3.10f1, 2021.1.9f1, 2021.2.0a17)
Could not test below Localization 0.11.0-preview due to System.AggregateException error when trying to Authorize

Notes:
-Trying to create a new spreadsheet outputs errors, due to Authorization not completing
