How do I change the wiper blades on my Vauxhall Zafira Life?

My wiper blades are not performing well and need to be replaced. I am unsure of how to do it myself, can someone provide step-by-step instructions?

First, lift the wiper arm away from the windshield and locate the small tab on the underside of the wiper blade. Press this tab and pull the blade down to detach it from the arm.

Next, remove the new wiper blade from its packaging and take note of the direction of the blade. Then, align the new blade with the wiper arm and slide it onto the arm until you hear a click. Make sure it is securely attached.

Finally, carefully lower the wiper arm back onto the windshield and test the new blade to ensure it is working properly. If it is not, double check the attachment and try again.
