[SOLVED] Help needed migrating node-red to docker

@bakman2 yes I know, I've already created a folder bound to the dockerized node-red.

@Colin Which kind of complications? I don't use node-red for lot of stuff, I made a pair of flows that "translate" tuya messages in MQTT for a better integration of some of my devices in Home Assistant.

I've already moved 99% of my flows on the dockerized node-red but I need find a way to bring back the 2FA. I shared my work here but I don't know how install passport-google-oauth20. in my external volume.
I've accessed the node-red bash and launched

npm install passport-google-oauth20

but i don't see new modules added in my /home/me/node-red-docker/ folder. Could you help me please?
