[MCU] Why didn't Fury call Captain Marvel during the Chitauri invasion?

Seriously is the invasion of New York City with gigantic alien worms led by a literal god not considered an "emergency" to Fury? Did he have that much faith in the avengers that he didn't even bother sending a message? Or was it that Danvers just ignored the message because she was in the middle of something?

- The Chitauri invasion was limited to New York and Fury had his own team by then. It was basically the first test, and they passed.

- While Fury has known that hostile aliens want the stones, Banner informed everyone of Thanos and his specific plan. It's safe to say that the team got in touch with Fury to let him know what was going on sometime up until the battle in Wakanda. 

- When Fury saw people turning into dust he knew that it meant his team had been defeated. No other choice at that point but to send the signal.
