Sql-server – how to script out proxy accounts

I have servers where I use proxy accounts to run ETL processes or even to backup SSAS databases using powershell through a job.

I can see what AD Accounts are related to my proxies:

use msdb
go

select 
    s.job_id
    ,s.name as [job_name]
    ,js.step_id
    ,js.step_name   
    ,js.subsystem
    ,js.proxy_id
    ,js.command
    , c.credential_identity
from sysjobs S
INNER JOIN sysjobsteps JS ON S.job_id = js.job_id
INNER JOIN sysproxies p ON js.proxy_id = p.proxy_id
INNER JOIN sys.credentials as c on c.credential_id = p.credential_id 

I can script out roles and logins and even table types but now I need to script out my proxies.

QUESTION:
How to script out proxies?

I Want to script out the following:

I have got this so far:

IF OBJECT_ID('TEMPDB..#tmp_sp_help_proxy','U') IS NOT NULL
   DROP TABLE #tmp_sp_help_proxy

create table #tmp_sp_help_proxy(proxy_id int null, 
                               name nvarchar(128) null, 
                               credential_identity nvarchar(128) null, 
                               enabled tinyint null, 
                               description nvarchar(1024) null, 
                               user_sid varbinary(40) null,  
                               credential_id int null, 
                               credential_identity_exists int null)

insert into #tmp_sp_help_proxy(proxy_id, name, credential_identity, enabled, description, user_sid, credential_id, credential_identity_exists) 
exec msdb.dbo.sp_help_proxy



SELECT
tshp.name AS [Name],
tshp.proxy_id AS [ID],
CAST(tshp.enabled AS bit) AS [IsEnabled],
ISNULL(tshp.description,N'''') AS [Description],
tshp.credential_id AS [CredentialID],
ISNULL(sc.name,N'''') AS [CredentialName],
ISNULL(tshp.credential_identity,N'''') AS [CredentialIdentity]
FROM
#tmp_sp_help_proxy AS tshp
INNER JOIN sys.credentials AS sc ON sc.credential_id = tshp.credential_id
