Accidentally deleted Mac partition in Bootcamp!

Hi!

So I've recently dug my old Macbook Pro out of my drawer, and remembered that I sort of messed up the computer. When I used Bootcamp in order to get Windows on the computer, I accidentally erased (or overwrote? not sure) the mac partition on the computer. It automatically boots into Windows now, and when I hold "option" on startup, the only available disk is "EFI Boot". I have tried Cmd+R, as well as Cmd+Option+R, and many other variations in hopes of accessing the "Internet Recovery" option. NOTHING has worked thus far.

Any thoughts? I do not care at all about keeping Windows, or my data. I am willing to have a full wipe of the computer if necessary if it means I can have normal macOS back on the laptop.

Let me know!
