How to get store.getters value in controller?

Question

Vue.js

I have a Nuxt SSR application, the architecture is as follows:
...
server
- controllers
-- client.controller.js
...
store
- client.js
- index.js

In index.js I store the agency id, which is set after authorization. How can I get this id in client.controller.js to list clients from the database for the current agency only? Suggest an idea, I can not understand in which direction to move.
