I can not find "Developer Tools" in UE5.4.4 ¿Where is it?

I need to check the memory in detail.
I have never seen my project use more than 4GB of memory.
But today it is using 13Gb of memory.
Something must be causing a memory leak.
It must be a material or a particle system because I haven’t written a single line of code today.

But, the statistics only show general characteristics.

And… I can not find “Developer Tools” in UE5.4.4

¿Where is it?
Any way to see the memory usage in details?
Thank you so much!!
