Is it possible to combine a DELL x1052p on the stack? How?

Hi!

Now I'm looking for switches for one of the offices and encountered a problem. I need four identical managed switches that can be combined into a stack. At the same time, the management set a condition for me, according to which each switch should not be more expensive than $ 1,500. Unfortunately, for some reason I do not understand, the choice of DELL switches is very small in THE country of which I am a citizen. I was able to find a DELL x1052p switch that fits the budget and there is a footnote in the description about the possibility of stacking. However, I doubt this, since I didn't find any typical ports on the switch case to stack.

For me, a typical combination of switches in a stack looks like this:

 In the DELL x1052p switch, as I understand it, it is suggested to use SFP ports for stacking. Have any of you ever faced the task of stacking these particular DELL x1052p switches? How is the process of stacking them? Maybe there is a video with an overview and a description of the process? If there is a link to the administration guide, it will be great.

Thanks.
