Help please….2004 toy 4Runner is chirping

Yesterday for the first time, my Toyota started making a chirping sound if I left the hood it sounds like it’s right behind the radiator where the drive belt is. It’s only there when I first start it. As it warms up, it only starts chirping when I press on the gas and then after about a half hour of driving it stops for right now.

Here are 2 videos of the sound

 

I'm not going to take a chance on downloading your videos just to be able to watch them, too much bad stuff out there...but just going by your description I'm going to guess the sound is either coming from a serpentine belt idler pulley bearing or tension pulley bearing or even possible it's the serpentine belt making the noise.
