Improve the incoming email handler to connect to Gmail with OAuth

In order to connect our Gmail account to the Jira Mail Handler, now we have to set the "Allow less secure app access" to be ON and use username and password to log in, which makes our Google account not secure enough. However, this way won't work anymore in the near future, since Google decided to change their authentication rules lately:

Access to LSAs will be turned off in two stages:

• After June 15, 2020 - Users who try to connect to an LSA for the first time will no longer be able to do so. This includes third-party apps that allow password-only access to Google calendars, contacts, and email via protocols such as CalDAV, CardDAV, IMAP, and Exchange ActiveSync (Google Sync). Users who have connected to LSAs prior to this date will be able to continue using them until usage of all LSAs is turned off. 
• After February 15, 2021 - Access to LSAs will be turned off for all G Suite accounts. 

Could you please let me know your plan about this?
