Nextcloud app reconize install models

I have a server running homeasistant OS and I installed Nextcloud from repository. With nextcloud installed and configured, I installed the reconize app to identify images, everything is configured but the app asks to run the occ recognize:download-models command to download the identification models, however the terminal does not recognize the commands. Could anyone help me with the nextcloud directory or how to execute the commands correctly? so I can make reconize work with your image identification?
