How reset all Interactive grid Filters Oracle APEX as Page Load Procedure from another page

Question

I have an Interactive Grid on "page 6" that I would like to reset from "page 7" with a Page Load Dynamic Action.

I have set the Static ID of the Interactive Grid to IR.

When I add this code to the page with the Interactive Grid "page 6" , it works fine and clears the filter.

apex.region("IR").widget().interactiveGrid("getActions").invoke("reset-report");

But when I try to add this in "page 4", I get the following error.

jQuery.Deferred exception: Cannot read properties of null (reading 'widget') TypeError: Cannot read properties of null (reading 'widget')
