Jenkins - set env var to output of a command?

I've inherited a Jenkins file and need to insert an environment variable. The variable is the output of the command:

openssl rand -base64 32

I've added it to the file like this:

sh('env.TF_VAR_sql_secret=$(openssl rand -base64 32)')

This outputs as I'd expect in the console:

env.SECRET=secretstuffhere

but running 'env' later on shows that this isn't actually set. So the command is working but I am messing up on the actual setting of the variable. I've also tried adding an 'environment' block as follows:

    environment {
        SECRET = """${sh(
            returnStdout: true,
            script: 'openssl rand -base64 32'
            )}""" 
    }

which returns an error:

env.SECRET=secretstuffhere: not found.

I really don't know what I'm doing with this but I feel I'm really close. It may have something to do with they way the jenkins file is structured?

The second block doesn't look correct. Like as you said, you were close to it.

    environment {
      SECRET = sh(script: 'openssl rand -base64 32', returnStdout: true) 
    }

Doing a println SECRET would give you the expected result as well W41NW9ly0kLsUgASJY7bpmSnqx5UYL6e2hefrMkrdIs=.
