Can I forward the WiFi hotspot to the local network to turn my PC into a WiFi access point?

This is how it works for me:

WIFI_SSID="test-ap"
WIFI_PSK="12345678"
sudo nmcli connection add \
    connection.id ap \
    type bridge \
    ifname br0 \
    bridge.stp no
sudo nmcli connection add \
    connection.id lan \
    type ethernet \
    master br0
sudo nmcli connection add \
    connection.id wlan \
    type wifi \
    master br0 \
    wifi.mode ap \
    wifi.ssid "${WIFI_SSID}" \
    wifi-sec.pairwise ccmp \
    wifi-sec.key-mgmt wpa-psk \
    wifi-sec.psk "${WIFI_PSK}"
sudo nmcli connection up ap
sudo nmcli connection up lan
sudo nmcli connection up wlan

Be sure to disable/remove other connections to avoid race conditions.
