Google assistant and Tasmota

Good afternoon

I have recently purchased a Tuya based smart switch, which I plan to install Tasmota onto, however before I do this, I want to know the following.

Can I use google assistant with Tasmota to turn the lights on and off via voice commands or does it need to go through HA. I have seen there is tasmota app will that integrate with google assistant or would I need to keep the stock firmware.

Any links to videos or guide would be helpful
