How to create a variable from hashtable value

Hi team.
I’m trying to create a variable from a hashtable value. If he logged on user matches the hashtable key, create the variable off the hashtable value.

# Create hashtable

$environments = @{  
'john.davies' = "IPC_john.davies"
# Variable for current user.

# Variable I'm trying to create. I'm not sure how to get it to return the associated value and create the variable from it.
$DeviceName = If ($environments.ContainsKey($env:UserName))

You refer to hash table values by their key.


would return
