PCB Layout - Bluetooth Antenna

Hello,
I made a breakout board for the STM32WB55 and want to use the bluetooth capability of it. Since I never did any layout with RF specs, I wanted to ask some experienced people wether or not the board I designed would 1.) boot up, and 2.) would be able to use the bluetooth feature. The top layer I filled with a ground plane whenever possible. And the bottom is covered with +3V3.

The antenna filter I used is a filter made for that very chip. Furthermore I want to use an onboard antenna, but not the pcb version. (Is that reasonable to do ?). My eyes fell on this antenna.

The board doesn't have to be bullet proof. I will power it with a bench supply. It is just for testing purposes to see if I could get every feature of the chip working.

EDIT: I attached the bottom and top layer of my 2 layer board, aswell as the schematics.

Actually, I just read up on a few things to look at when designing pcb's with RF things on it. I will redesign the mess above and come back later.
