Teckin smart plug SP21

Hi,
Someone familiar with the smart plugs sp21 from Teckin, would like to ad them to my Homey, but I still can not find a way how, there is nothing about Teckin in the Homey apps.
Here a link of the plugs:WLAN Smart Steckdose Intelligente Mini Plug TECKIN Alexa Wifi Steckdose fernbedienbar, funktioniert mit Amaon Alexa und Google Home, mit App Steurung überall und zu jeder Zeit - 3 Packs https://www.amazon.de/dp/B07HHFKWJJ/ref=cm_sw_r_cp_apa_i_-ptjCbTB4Z9HW
Been able to link them in Google home.

Wel you need a app for it.

Are Teckin WIFi smart plugs just re-branded white-label tech like Tuya stuff?

I was looking at the SP23 set in the hope they could be controlled through Homey too – https://amzn.to/37bdbb5

@Tibor070 did you get anywhere 2 years ago with adding the SP21 to Homey?
