Editing bash prompt for virtual environment and working directory

I am using bash on MacBook Air and I want to colourise the terminal prompt so that it stands out from the other output that is created.

It looked like this:

I was helped on another question till I used export PS1="\e[0;33m\h:\w \u\$ \e[m" which changed the colour but the prompt doesn't have (base) in it. It is the virtual environments I created using conda. conda deactivate is used to remove it and conda activate env2 for activating environment env2.

  1. What can I include to have the (base) there?

  2. What would make it Desktop, not ~/Desktop?

Kindly suggest changes to the above line only, I am not experienced enough for scripts etc.
