Annotated Heatmap with Webgl?

I am using Plotly Annotated Heatmap, but with a large dataset.

The problem is that Dash visualization is ver very slow and so it makes no sense for data analysis.
Im trying using WebGL to make it faster, as the examples showed with normal heatmaps, but graph_objects seems not to have annotates heatmaps(only normal ones), so im going crazy searching for a solution.

I’ve been searching in plotlys git and I want something like this:
WebGL Text and Annotations | Python/v3 | Plotly (AGCT annotated heatmap)

The problem with this example is that is dreprecated and I cant find the trace dict documentation.
