What is the exact value of internal reference temperature coefficient in STM32WB55RGV6 Bluetooth 5 MCU?

Hello. What is the exact value of T_coeff_vrefint? I'm planning to use internal reference voltage buffer (VREFBUF) output pin in my application.

One more question: is V_ref voltage equal to 1,212 V or to 2,048 V / 2,5 V?
