Find flows where a certain variable is used

in previous homey releases this was not possible, but is there now a way natively or using a script to find all flows where a certain variable is used ?

Not with a built in Homey tool, but it is possible, for a long time actually, with this community app card:

It takes variables as “object type” and it can filter results by var name.

The Flow Checker app provides information about variables.
