zoom is not working

[pancodia]

I am using this package to embed a flowchart in my sphinx doc. My mermaid code is in a separate file. I sourced the file as

.. mermaid:: ./data_pipeline.mmd

In the generated html, I can see the diagram. However, I cannot zoom in or out.

The following is my configuration for the package in conf.py:

# ------------ Mermaid configuration --------------------------------
mermaid_output_format = 'svg'
mermaid_cmd = '/Users/pachao/.asdf/shims/mmdc'
mermaid_d3_zoom = True

The following are my package versions (I am using pydata-sphinx-theme):

$ pip3 show sphinxcontrib-mermaid sphinx
Name: sphinxcontrib-mermaid
Version: 0.9.2

Name: Sphinx
Version: 7.0.1

Name: pydata-sphinx-theme
Version: 0.13.3

How would you suggest me to debug the issue?
