Missing piece in the workflow

After finding the event, that I want to see the odds for, I do not know, which bookmaker offers odds for this event. This is a whole in the pipeline I would like to build.
My suggestion: It would be great, if https://api.odds-api.io/v3/events would return the available bookmakers (incl. slugs).
A workflow can then pick a bookmaker slug and fetch from https://api.odds-api.io/v3/odds, where the bookmakers slug is actually a required param.
Best, Pascal
