There is a missing component in this circuit and couldn’t figure out why


I'm designing a BA1404 Stereo FM transmitter and I found the following source: Source Link

You can find the component list, circuit scheme and the other stuff on this page. But when I look at the scheme, I couldn't find the 10uH Inductor on it. There are some images of the assembled circuit board and you can see the 10uH Inductor on the board.

I'm totally new at electrical circuits. Am I missing something at the scheme? By the way, are there some other sources on the internet where I saw the same circuit and similar assembled boards?

It's definitely on the board (the green component on the top right), but not in the schematic. My guess, based on its positioning, is that it's part of the power supply filtering.
