Bangla Keybord not showing in clear Linux by deafult

I am From India my mother toung is Bangla, I use Provat Bangla Keyboard for typing but i try lot of way just I can install Openbangla keyboard, please help me to install my keybord layouts

they seem to provide a bash command to install?

bash -c "$(wget -q https://raw.githubusercontent.com/OpenBangla/OpenBangla-Keyboard/master/tools/install.sh -O -)"

You could also build it from source

EDIT: due to the fact that there is a submodule called riti which uses rust, I dont recommend trying to use autospec. the submodule needs a vendor. (its doable but kinda a pain)

Very sorry to say its now works i tried lot of time,
