Convert categorical to string

I have two categorical column vectors of size 872-by-1. I want to calculate the Levenshtein distance between these two. When I am using the command 'editDistance' for this I am getting an error as

"Argument 1 must be a string array, a character vector, or a cell array of character vectors."

After searching the solution for this problem, I thought to convert it to string, but I am not getting a way for this. How can I convert categorical column vector to string? or how can I resolve the error?

In case of any query feel free to comment.

V1 = categorical([1,2,3,2,2,1])

V1 = 1×6 categorical array
     1      2      3      2      2      1 

V2 = categorical([3,1,2,2,1,1])

V2 = 1×6 categorical array
     3      1      2      2      1      1 

S1 = string(V1)

S1 = 1×6 string array
    "1"    "2"    "3"    "2"    "2"    "1"

S2 = string(V2)

S2 = 1×6 string array
    "3"    "1"    "2"    "2"    "1"    "1"
