How to make the part of label outside frame invisible

[ItzBloxyDev]

Hello,
I want to create a label slide out of the frame and while the frame is sliding the parts of the label that are outside of the frame are invisible.

Here is an example, the bit inside the red circle should be invisible since it is not inside the frame. It would be greatly appreciated if you could help.
Thank you in advance

Enable ClipDescendants on the Frame.
