Control unsupported devices via supported buttons

Hello everyone, I’m quite new to homeassistant and have a couple of Magic Home bulbs (not MagicHue) and I have read some posts on integrating that bulb and someone had success and others didn’t. The bulb needs to be unlocked from the Broadlink app but the bulbs can’t connect to it, they only connect to the Magic Home app. Since these bulbs work with Alexa, I assume it is possible to create a fake sensor activated with one of those little buttons in HA and link it to Alexa which then can be used as a trigger for turning on the lights. Can you tell me if it’s possible and if it is, how do I go about doing this? Thank you in advance.
