Using the --tags option with @elastic/synthetics

Any hints to correctly using the --tags option with @elastic/synthetics?

Assuming a journey where I've added monitors.use({ tags: ["foo", "bar"] })

If I run npx @elastic/synthetics . --tags "foo" I get No tests found!

I've tried permutations with --tags like --tags "[foo]" and --tags "['foo']" and --tags foo but get the same No tests found! result.

What's the correct syntax for using the --tags option?

Bumping this. Still haven't gotten the --tags to work as expected, or haven't clearly understood how it's supposed to work. Can anyone provide insight?

Apologies for delay, we have an issue open to address this
