It is possible to create WiFi Access Points with the network-manager snap. This can be done by running
$ nmcli d wifi hotspot ifname <wifi_iface> ssid <ssid> password <password>
where <wifi_iface> is the wifi network interface, <ssid> is the SSID for the AP that we are creating and that will be visible to devices connecting to it, and <password> is the access password (that needs to have between 8-63 characters or 64 hexadecimal characters). NM will create a connection called ’ Hotspot <N> ’ if the command is successful.
The created AP offers by default a shared connection, so devices connected to it should be able to access the Internet if the device providing the AP has access too.
