Unable to disconnect battery connector in my Asus Laptop

I have watched multiple videos where when they moved the slider, the white battery connector just pops out. However, mine just stays in place and does not budge when I try to move it. Am I doing something wrong or is there something wrong with the laptop? This is what it looks like
