How do I extract data point from a cell inside a heatmap?

I created a heatmap using the "heatmap" function by feeding a 2-dim matrix. I see I can click into each heatmap cell and show the x name, y name and the value. I am just wondering how I can click into the cell and extract these information (e.g. store them into a variable and use them for other calculations?)

I'm sure there's a way to develop something that does this graphically, but I would use groupsummary to create the heatmap results.

load patients
tbl = table(LastName,Age,Gender,SelfAssessedHealthStatus,...
    Smoker,Weight,Location);
heatmap(tbl,'Smoker','SelfAssessedHealthStatus')

●

heatTbl = groupsummary(tbl,{'Smoker','SelfAssessedHealthStatus'})

heatTbl = 8x3 table
    Smoker    SelfAssessedHealthStatus    GroupCount

    true           {'Poor'     }               3
