Tooltip labels in pydeck, with info from dataframe

I’m not being able to send infomation to the tooltip of an pydeck graph. I’am using a table that i get from an sql query, with this fields:
latitude, longitude, location descriptio and value.
I would like to send the location description to the tooltip, but it just not showing up. Does anyone has this properly working, and could send me an example?

Best regards,
Miguel
