How to add the Total Blocking Time (TBT) metrics in grafana?

Hi !
Here’s my problem :
I would like to add the Total Blocking Time (TBT) (https://web.dev/tbt/) but I don’t know what to put in the grafana query…
I am using Docker and Graphite.

Here are the metrics provided by graphite (ConfiguredMetrics.txt) :

Here is a query for the Cumulative Layout Shift (CLS) :

aliasByNode(sortBy($namespace.$path.pageSummary.$domains.$pages.$browser.$connectivity.browsertime.statistics.pageinfo.layoutShift.$function, 'average'),3, 4)
