Setting up GMB map Adwords

I've got an existing Adwords account that's been running for years; it's all setup and running fine. I want to start advertising on Google Maps but I can't work out what the correct type of ad is required to use.

I'd like an experienced Google Adwords marketer to jump in to my account and setup an ad campaign to appear on Google Maps and walk me through which type of ad you used. No other ongoing monitoring of the ads is required.
