How can I get Grafana Dashboard variables in Panel Javascript？

How can I get Grafana Dashboard variables, such as the $__from variable, in the Echarts panel? When I use the following JavaScript code to get this variable, I can’t retrieve it. However, it can be displayed in the panel title.

Use the replaceVariables() function to replace dashboard and global variables.

const from = replaceVariables("${__from}");

See documentation:
