Scroll Reach doesn't allow multiple % values

When following the details to migrate from Google TagManager into Matomo TagManager I get problems to set Scroll Reach to use multiple percentage values

Steps:

  1. Create a new trigger >> Scroll Reach type
  2. Scroll Match Type >> Vertical - Percentage
  3. Percentage >> Value set same as in example “20, 40, 75, 90”

Error: Percentage: The value is not a number.

I was expecting to be able to create the same as in GTM where I can put multiple values for Scroll Depth trigger type. Do I understand wrongly this?

is the solution to create multiple triggers all with the different percentage needed?
