some evaporation of the coolant in the expansion tank is to be expected. Your car is a 2015 and if you never checked your coolant level you've probably been letting it go down gradually for years. then again, you say green when original coolant is blue, so someone has been in there between then and now...
If the coolant level in the metal cap was full... ???

i open the radiator cap and i can see there is some green coolant around the cap, i guess it means there was some level of coolant on the radiator.

I dunno, was it full? coolant
around the cap? There was
some level? what level? high level? mid level? low level? just "some" level? As in kinda there~ish? sorta like eyeballin' it with the hood closed from across the street??? And "on" the radiator?
Your issue is probably with the fan. More than anything, if the needle is above the middle of the gauge the fan should be running, if it's not running start by getting it to run, because no matter how much coolant is in it or not, if it's hot, it should be trying to cool itself.
