Thunderbird email notifications disappear too quickly

[muhMoz11]

I am using Thunderbird 140.8.0esr (64-bit).
When I receive an email, a notification appears in the top right corner of the screen. It disappears too quickly. In the Settings, it would be very useful if there were two options added:
1) duration of notification in seconds
2) notification remains displayed until manually closed
Another possibility would be if the notifications conformed to the settings defined in the notifications widget in the taskbar (I am running Linux Mint 22.3 - Cinnamon 64-bit).
