Creating a New API key for Retail

Could someone please inform me where I can create an api key for my lightspeed system . According to support only advance or professional subscription package holder (I have advanced) can only use api. I am trying to create an API key for Modern Retail https://support.modernretail.com/hc/en-us/articles/205199407-Generating-an-API-Key?mobile_site=true
Thanks

Hello @PenuelBicycles,
We deprecated the use of API Keys since the beginning of last year. The integration should use their OAuth Client in order to create an access token to get access to your data.
