Hello @Niki_Nagar
The Lora-E5 mini is made by a third party based on the STM32WLE5JC MCU. So, for such a question is better to go and ask the same question on the Forum of our third party (on this link). For the P2P examples using this module, you can maybe find some examples (No guarantee by ST) such as this one. For documentation of this module, they are available here (in the end of the page). For Documentation on the STM32WLE, you can find everything you need here and for the Cube Package used for this MCU you can find it here.
Best Regards.
STTwo-32
