Query timerange from a influxdb tag and use it as variable for a second query

InfluxDB 2
,
2

hint:

Referencing “_time” from previous query as “range(start: , stop:now())” for a following query. I can’t get it to work - InfluxDB 2 - InfluxData Community Forums

If I have some free time I will return with the solution, I have done what you are asking multiple times…
