Just for the experiment I tested the app.
Suffice the necessary dependencies are synced - it works as expected.
I banged a wall at first - but then I realized my firewall would block - when I disabled firewall - I couls connect my phone the default hotspot.
My system is on unstable branch (custom scripts often require arch package level)
$ inxi -Sxxxc0
System:
Host: fox13 Kernel: 6.12.10-1-MANJARO arch: x86_64 bits: 64

$ pacman-mirrors --get-branch
unstable
dnsmasq is a required dependency
apparmor is a required dependency
See → AppArmor - ArchWiki
For apparmor to work correct you need adding to kernel cmdline.
lsm=landlock,lockdown,yama,integrity,apparmor,bpf
rebuild init and reboot
sudo mkinitcpio -P
