How do I add tempo markings?

[ego-lay-atman-bay]

I've tried adding tempo markings by using this

let staveTempo = new StaveTempo(tempo.starting)
staveTempo.setTempo({
    bpm: tempo,
})
tempo.setContext(context).draw(stave)

But it doesn't seem to render. I checked in the dev tools, and there's no additional element for the tempo, which is why I'm here, I would like to know how to add tempo marking, because I can't find much about it.

edit: I just tried

stave.setTempo(tempo)

which also didn't work

I just figured it out, I had to do this

stave.setTempo({
    bpm: tempo
    duration: 'q',
})

Have a look at the tempo tests in stave_tests.ts
