Remove "excess" after applying kriging interpolation

Apologies if this is not the correct place, or if this has been answered before, but I am new to ArcGIS so struggling a bit.

I have points with precipitation values, and I have applied kriging from the interpolation tools so that I have an interpolated precipitation surface for Thailand.

However, this has been done to a rectangle about the same size as Thailand, so includes areas that are ocean/other countries that I am not interested in.

Is there a way to only display the interpolation within Thailand?

I have (hopefully attached the example of the current map I have). I want to have everything inside the black line depicting the border or Thailand.

Thanks in advance! (Also, I am very new to all of this, and teaching myself, so please explain things in a very basic step-by-step way).
