Eu finalmente consegui com a ajuda de create_ap ! Aqui está o que eu fiz:
#Install dependencies:
sudo apt install git && sudo apt-get install make && sudo apt-get install hostapd
#Install create_ap:
git clone https://github.com/oblique/create_ap
cd create_ap
make install
#Make Config File:
sudo create_ap -n wlan0 -g 192.168.0.1 MyAccessPoint MyPassPhrase --mkconfig /etc/create_ap.conf
#Start the systemd service:
sudo systemctl start create_ap
#Enable the service to start on boot:
sudo systemctl enable create_ap
