How to Install Matplotlib using Conda.jl in Julia-1.7.3

I was having a trouble of plotting with:

using Plots
pyplot()

I create a folder to run my environment when I cd to that folder and type:

julia --project="."

Then I check my package status with ] st:

Status ~/LasthrimProjection/ijuliaenv/Project.toml [8f4d0f93] Conda v1.7.0 [438e738f] PyCall v1.93.1 [d330b81b] PyPlot v2.10.0

I try this code :

using Plots
pyplot()

x=range(-2,stop=2,length=100)
y=range(sqrt(2),stop=2,length=100)
f(x,y) = x*y-x-y+1
plot(x,y,f,st=:surface,camera=(-30,30))

I get this warning (I already build PyPlot and PyCall multiple times):

Warning: You are using Matplotlib 3.3.4, which is no longer │ officialy supported by the Plots community.

If I use Jupyter Notebook with Python kernel and I do :

pip install matplotlib

I get matplotlib-3.5.2, it is installed at /home/browni/.julia/conda/3/lib/python3.9/site-packages.

The problem still persists to plot with pyplot().

Hopefully someone can help me here. Why would PyError look for python3.6 (python from system instead of Python inside Conda inside Julia?)
