Font Size Git Graph Commits

[darena-patrick]

Greetings, I am attempting to increase the font size of the commits on the following diagram ... is that possible? I can change the titles, but it doesn't seem like the small labels can be edited.

%%{init: {'theme': 'base', 'themeVariables': { 'primaryColor': '#FFFFFF', 'lineColor' : '#CC0000', 'fontSize': '20px' }}}%%
gitGraph:
    commit id: "1"
    commit id: "2"
    branch featureA
    checkout featureA
    commit id: "3'"
    commit id: "4'"
    checkout main
    merge featureA
