How to insert algorithm pseudocode in Lyx?

I have found the answer:

1. add the \usepackage{algorithm,algpseudocode} into the premble
2. insert a algorithm block (Insert --> Floating --> Algorithm)
3. insert the tex code in the algorithm block (Insert --> Tex Code)

4. add the following latex code

   \begin{algorithmic}[1]
   \Require{$\rho \geq 1$}
   \Ensure{$X_k$}
   \While{not converged}
   \State{Solve $X_{k+1}=\min_{X} L(X,Y_k, \mu_k)$}
   \State{$Y_{k+1}=Y_k+\mu_k h(X_{k+1})$}
   \State{$\mu_{k+1}=\rho \mu_k$}
   \EndWhile
   \end{algorithmic}
   

LyX Version 2.3.4.3(Windows 10) (14 February 2020)

1. Insert->float->Algorithm
2. Change Environment choice box (in this version it is just below file menu) from Standard to LyX-code
3. Type the pseudo-code inside the box as you would in an editor. Math formatting works as usual. To highlight keywords select text and press Ctrl+b.
