STM32G031G6Ux(UFQFPN28) has no pin to connect external crystal oscillator?

I have a project using STM32G031G6Ux(UFQFPN28), so in CubeMX I could not find the external crystal oscillator pins.So I want to know that whether this MCU  has the pin to connect external crystal oscillator?

Dose there have any documents about the design about this MCU,thanks.

It is expected as part of keeping the board size down that you reuse an existing clock source, ie TCXO for radio, or whatever, or that you use the internal oscillator

It has an OSC_IN on PC14, but no OSC_OUT pin. So you can hook it up to a clock source but it can't drive a crystal directly.

Details are in the datasheet:
