Approval Process - E-Mail notification

Hello experts,

in C4C it is possible to create e-mail notifications so that a approver gets an e-mail when there is a sales quote to approve - see picture below.

Now we have the customer requirments that we want our own text into this e-mail. Unfortunately I don't find the concerning e-mail template in C4C where I can change the body text of the e-mail. Please could you help me?

Thanks,

Kind Regards

Jasmin
