How we can use Chart.helpers in custom tooltip plugin with external option

[mahadev-Pandhare]

Hi Team,
Currently we are using Chart js3.6.2 version in our Project where we have requirement of line chart with custom tooltip.
For custom tool tip we refered example from link :https://www.chartjs.org/docs/3.6.2/configuration/tooltip.html

But we are getting issue with Chart.helpers.toFont(tooltipModel.options.bodyFont);
i am getting error with the helpers are not available . So can please let us know how we can use helpers in latest version with source code with import statements Please.

Thanks,
M.dev
