r Heatmap values in cells - package ComplexHeatmap

Question

I have a small matrix with numbers that I want to trnsfer into a heatmap and keep the numbers inside. This is the data:

print(cor.matrix)
          stock.GLS stock.NVS stock.PLX
stock.GLS 1.0000000 0.4078177 0.2416839
stock.NVS 0.4078177 1.0000000 0.1485917
stock.PLX 0.2416839 0.1485917 1.0000000

And this is how I make the heatmap.

I want the numbers to go inside the squares like here [ display a matrix, including the values, as a heatmap , but using this package. Any idea?

library(ComplexHeatmap)

Heatmap(cor.matrix, 
        cluster_columns=FALSE,
        cluster_rows=FALSE
       )

The output looks like this:
