Using Anima plugin with Figma to make a responsive website

Hello everyone.
I am trying to use the Anima plugin in Figma to make a responsive website.
I watched the tutorial provided by Anima, but it didn’t work.
After finishing the design in two different screen sizes Desktop (1440 * 1024) and mobile (375 * 667). I signed up with Anima. The steps I followed were like this:
1- I clicked on the plugins, then I clicked on Anima.
2- I ran Anima, then I chose the desktop and the mobile frames by holding Shift-key.
3- I tried to create a breakpoint to make the responsivity but nothing worked after that.

Hi @Tawfeeq have you clicked “save” after adding breakpoints? Please, also make sure that the names of frames for two screens match.
