Allow for syncing Proton Calendar with Thunderbird, which is the client I use for PM emails on my iMac.
Proton calendar currently does not have support for 3rd party apps, such as Thunderbird. I use Thunderbird with all of my PM email addresses and do not want to have another app open it is convenient from my personal and freelance work emails to be all in one place.

I agree. I use em client and have to have the Proton desktop client running also. But Proton mail also runs and I get 2 notifications for every email. You can already use Proton Bridge to add Proton mail to 3rd party clients, please add calendar to it.

As a Thunderbird user (and currently editing my Google calendar from Thunderbird) I'd say this would be a welcome feature.
