telegram support

when I try to enable telegram support in the traccar.xml file I get an error on startup:

Do you see anything different between how database properties are defined and your telegram stuff is defined?

ah yes, looks like those should be within the properties tag. thanks!

While telegram notifications are working now. I notice that the web notification channel is now missing from the notifications. How do I add it back?

That's because you set types to "telegram" only.

You only enabled telegram:

<entry key='notificator.types'>telegram</entry>

try:

<entry key='notificator.types'>telegram,web</entry>
