Dynamicly setting Slider's value

Hello users

I want to make an animated plot.
I have done it with slider.
And now I want to make a “Play” button so that slider will move from left to right at some speed.

So the problem I faced to is that I can set slider value but it doesn’t call slider’s callback and it isn’t visualized (slider doesn’t change it’s position).

So is there any solution for this problem?

P.s. attached the code where I tried to manipulate the second slider using the first slider (actually I’m trying to make the second slider moving the same way as the first one)
