Latest update, I have finally managed to sort it out using the terminal and those commands, adapting it based on my needs.
nmcli c add type wifi ifname wifi-device con-name connection-name autoconnect no ssid hotspot-ssid
nmcli connection modify connection-name 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared
nmcli connection modify connection-name wifi-sec.key-mgmt wpa-psk
nmcli connection modify connection-name wifi-sec.psk "le password"
nmcli connection up connection-name
This new connection is working properly.
My guess is that the uuid was needed and I didn't included it ><
from there, switching connection will be very easy with the commands
nmcli connection down connection1
nmcli connection up connection2
thank's a lot.
I would need your help for the next step for sure.
