what does it mean about 'Button connected to pin 3 and GND.'

hi, I am doing the emoji_button.ino project. I am confused about the 'Button connected to pin 3 and GND.'

Do I need to insert my Nano 33 BLE Sense board into the TinyShield? or use a jumper to connect Pin3 and GND? I am not sure. I will appreciate it if you could relpy.

从 emoji_button.ino 项目以及说明按钮连接到 pin 3 和 GND 的指示开始。检查项目的硬件设置文档以及对 board 或 TinyShield 的引用，以确定预期的接线方式。完成的标准是：说明清楚解释所需的 board 连接，以及是否需要 jumper 或 shield。
