Esptool and Thonny

Another day another problem :-)
I am trying to install micropython on an esp32 with Thonny I’m using a Rasperry Pi 5 but every time I try I get an error with Thonny saying esptool is not installed use tools >-Manage plugins but it’s not there.
So I went through the setting up a esptoolsenv and opened thonny in that and it still can not install micropython it comes back with the same screen download it from tools

So my question is how do I load micropython on an esp32 with a raspberry pi 5

Thanks all
