We extract event report with param name action & label by querying below in Bigquery
#standardSQL
select
event_name,
param1.value.string_value as action,
param2.value.string_value as label,
count(1) as eventcount
From `<table>`,
UNNEST(event_params) as param1,
UNNEST(event_params) as param2
where event_name = 'BotNav'
and param1.key='action'
and param2.key='label'
group by 1, 2, 3
order by eventcount desc
