Seeeduino Lotus not on Arduino IDE

Hello everyone,

I got a Seeeduino Lotus a year ago as a gift and I thought I would finally try to figure this thing out, but I am in need of help. Upon following the tutorial for the setup it is stated that the Seeeduino Lotus board can be selected in the API under tools and then boards.

My problem is I cannot seem to find any Seeeduino boards. I have looked at other forum posts to install extra boards by pasting a link under preferences, but none of these external boards are the Lotus.

If anyone can help me to add my Lotus to the API it would be much appreciated, thank you.
