Use LSI or HSI as the clock source of RF unit in STM32WB55

To use a clock to drive the RF unit of the STM32WB55, here are 2 options in the BLE_p2pServer demo code, LSE and HSE divided by 1024,

I want to know if it is available to use LSI or HSI as the clock source of RF unit in it, thank you.

Only LSE and HSE/1024 are available as an RF wakeup clock source on this chip per the reference manual.
