AWS cloudformation - get substring-CodePudding

I just start to use AWS cloudformation and I got a block as below:

I have a string

string = redundant_value/12b4/xyz/succes

And I want to get 12b4/xyz/succes of the string. How would I get it?

my illustration here

Another example for my question:

${string} = abcd/123xx/OBcs/azy_cd

how would I get only 123xx/OBcs/azy_cd from ${string}

Can I do this?

fn::Split: ['abcd/', ${string}] = [123xx/OBcs/azy_cd]
fn::Select: [0, [123xx/OBcs/azy_cd]]

I have read there is a method about Fn::Sub. But I am not able to understand it yet.
