Cannot find the selector in Find Children

I’m trying to extract the experience section from the LinkedIn website and every time there is a ‘see more’ it has to click on that and extract that as well. I’ve used Find Children activity but when I run the file, it says ‘selector not found.’
Can someone help me resolve this issue?
Thank you!

Try to get the selector from ui explorer and like select the main block so that you will entire all the selector and then take required selector and why u r using find children for to click use element exist and then click activity???

I’m extracting the whole data using get full text activity, but some of the experience sections have ‘see more’ and I need the full data. Hence, I’m using find children activity.

Okay first check element exist for see more is there or not if it is there click it and then use get the full text
