I added a pointed finger in one of my videos to indicate where something is.
At the top click on Add Objects, select Clip Art library, Then select Icons and Symbols, Select Arrows, on there you will find pointed finger, you can make it as large or small as you like and change it's direction, Or you could just use an arrow, they're all on there
Here is the use of the pointing finger, it comes at the end of the video....https://youtu.be/LHmIBUYKVBA
