Alexa light commands for white lights

I’m a noob and I’m trying to figure out how to add bright and dim setting commands to Alexa for my zha lights. Can anyone help me with a flow for this?

use the node-red-contrib-alexa-remote2 node

you can send custom messages with the routine node. If you look a the node info it gives an example of sending smarthome commands for on/off, brightness and colour

Will this work with node red used on home assistant?

I would think so, i do not have HA so can not tell you difinitively. Try it an see.
