Replace Tag value

Hello,

I have a Tag in Azure, it ia called Descritpion. Ths field has a lot of values.

Some values are:

Applikation - Ressources Software 1 or Applikation - Ressources Software 2 or Applikation - Ressources Software 3....

No I want to replace the the values Applikation - Ressources with Applcation - Resources. The values behind this string should be the same as bevour.

I hope somebody can help me,

Horst
