How to send a command to chroot as another user?

Question

linux

Hello. You need to run a socket server in the root, which will work all the time. Runs in the screen.
A separate user is created for it. There are several of them in the system.
/home/sockets/ socket1 /
/home/sockets/ socket2 /
...
/home/socket/ socket32 /
They have system images for chroot in their directories.
Well, there are socket1, socket2, socket32 users in the system.
Tell me how, being under the root in the system, send a command to start a socket in /home/sockets/ socket1 / in the screen with the necessary parameters and arguments on behalf of the socket1 user.
That is, so that the command in the chroot is executed on behalf of socket1, and not the chroot itself is executed from it.
