Comment:

 But it didn't work for me. It would be great if the underlying problem can
 be fixed in this case. Posting logs in case it helps.

 Here is the command I executed:
 ffmpeg -i .Files/1szqpq/hjmuqD/creation/overlaid-video.mp4 -itsoffset
 22.952 -i
 .Files/1szqpq/hjmuqD/creation/07eda82db409f6c212ffa829287d9c0d_clip.webm
 -filter_complex "overlay=x='if(gte(t,34.28),NAN,0)':y=0" -y
 .Files/1szqpq/hjmuqD/creation/overlaid-video-2.mp4
