Hi @RCron.1 i am in your same situation, still not bald tough..
(but closer each day)
Some of the example projects have prebuilds for all supported platforms (including cubeIDE) like BLEcablereplacement
(\STM32Cube\Repository\STM32Cube_FW_WB_V1.12.1\Projects\P-NUCLEO-WB55.Nucleo\Applications\BLE\BLE_CableReplacement)
