For text:
You use your mouse to click on the percentage button that is next to the text color. Here in the above image, that is the “98%” small button.
After you click on the button, there will be a color picker for you to change the color properties. Please look at the image below and you will see that there is a small bar. The bar is used to change the opacity of text. You can move to change the opacity value as you want.
For Logos:
You can change the opacity of logos by changing the value in the opacity small bar. You use and hold the left click to move and change the opacity value.
