How to catch Flashing Text on the web

Hi to All,

I have a project that has many steps in it.
The step where I have a problem is to get Flashing Text on the website (which is a warning)
and if I see this warning text I have to change my steps.

First, i tried this by getting “image exists” activity and put the output variable in IF condition. But this activity doesn’t recognize that flashing text.

Then, secondly used Element exists activity
( - first checked whether there is a kind of element if any flashing text was not there, and yes there was not, so thought it may work
and used again in if condition but there again a problem occurred. It always acts like there is the element.

So now get stuck and dont know what to do.

I need your help, please, thank you
