Tuta Calendar Thunderbird Integration

AlternativeTo reported that email provider Tuta has released mail and calendar add-ons for Thunderbird. I have a cheap Tuta account (so cheap it is no longer available, thank you grandfathering) that I have not used in several years, not least because Tuta does not support IMAP (this is also why I have not seriously considered Proton Mail, despite its Proton Bridge work-around). While that will continue to lead to me not relying on it as a main email account, I may give the calendar a spin since I have never really used a digital calendar anyway and I suppose that is a good use-case if I am keeping the account. If it works out, I do have my Tuta email configured with SimpleLogin, so I suppose I could point some “scheduling” emails at it.

(For anyone who may be curious, I tried Tuta back in late 2020 or so when I was deciding on a new email provider. As I noted recently, my main email set-up is Posteo + SimpleLogin.)
