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,
