Starting applications or binaries inside the container

lxc version: 3.0.2
Working with unprivilaged container

I have already created a container
I have some binaries placed on the host, those folders are bind mounted inside the container rfs
I am starting the container as a systemd service.
Now i want to start the applications also from the service files.

I can login as my unprivialged user, start and attach to the container and start the binary . it works and there is no problem.

Is there any way that i can run the applications inside the container without logging in as unprivileged user and attaching to the container?
