+Connect the [`process-control`](https://snapcraft.io/docs/process-control-interface) interface for system-wide process management. This is needed to grant Chip Tool access to make [sched_setattr](https://man7.org/linux/man-pages/man2/sched_setattr.2.html) system calls. This may improve the reliability of the operations (see https://github.com/canonical/chip-tool-snap/issues/8).
