Moving camera when mouse gets to edge of screen

Hello, I am very new to Gdevelop and new to trying to make a game. I was wondering if anyone could help…

I would like to move the camera to when the mouse pointer reaches the screen edges.

Or if the mouse touches the sprites with anchors at the edges, or the mouse check is greater than the marked position. There needs a separate camera.
Then you move the camera along x, y.

P.S. English is not my native language, sorry for mistakes

I’ve tried this mouse move screen - #6 by MrMen and had no luck.

Can you provide a screenshot of your code, so we can see what’s going on?

I tried another solution and somewhat achieved the same idea. I will post some screenshots when I get back to my pc. I am now going to use a click and drag to move the camera view around. It actually works very well in touchscreen. I might still have some issues with dragging my objects (cards) around. I will have more info. Thanks for your time so far, im sure I will run into a few problems as I am learning
