Can't get project with Notifications V2 to compile

Hi,

I manually added the Notifications V2 plugin to my old Corona Enterprise project.

However, when I try to build, I get the following build error:

Undefined symbols for architecture arm64:

  “CoronaBeacon::IMPRESSION”, referenced from:

      ___49-[CoronaNotificationsPluginDelegate connectToFCM]_block_invoke in libNotificationsV2Plugin.a(NotificationsV2Plugin.o)

  “CoronaBeacon::sendDeviceDataToBeacon(lua_State*, char const*, char const*, char const*, char const*, int (*)(lua_State*))”, referenced from:

      ___49-[CoronaNotificationsPluginDelegate connectToFCM]_block_invoke in libNotificationsV2Plugin.a(NotificationsV2Plugin.o)

I’ve tried to search for a solution but can’t find one and am stuck. Does anyone know how to get it running?
