When will an ESR version of Thunderbird with Microsoft Graph support be available

I have had messages about EWS support being ended from 1st October from the Beonex ExQuilla Add-On which I have been using for many years. So I installed Beonex's new Owl Add-On which supports Microsoft Graph Protocol and migrated my Email accounts. However, this just renamed my existing account with "Old" at the end and created new ones which cannot connect! The IT provider for the Email Domain will not allow the Owl Beonex App to connect, despite the ExQuilla one being used for many years! They have now pointed out that Thunderbird natively supports the Microsoft Graph Protocol from Release 154. BUT I am on the ESR channel (as I need stable Email handling) and the latest ESR Release is 153.4.0esr! '''So when will an ESR be released with Graph Support, as Microsoft could stop me being able to receive and send Emails any day as it is now past 1st October????''' - Please let me know your timeline for the next ESR with Graph support A.S.A.P. I do not want to install a non-ESR as I see that the latest Release 157.0.1 fixed a bug with the Graph protocol and 155.0 streamlined the manual account configuration. So I want stick with stable releases! Also, do I have to add new accounts to use Microsoft Graph, or can I just change the configuration of my existing ones? If the former, then I guess once I am happy I have all old Emails available (as I rely on Emails going back many years!), I can delete the original Accounts from Thunderbird, including the non-working " Old" ones created by the ExQuilla to Owl migration???? Thanks
