Can't show lint error in custom linter rules plugin - Camunda Platform 7

Hi,
I am using camunda-modeler-custom-linter-rules-plugin with custom rules in Camunda Modeler 5.5.1. Just downloaded, installed with npm install and built with npm run all. In BPMN diagram created in Platform 8 it is working fine.
Hoewer when I click on linting error in Platform 7 it shows this bug:

showLintError is not a registered action

This error may be the result of a plug-in compatibility issue. [ info ]

Is Platform 7 supported by this plugin or there is a bug somewhere?

I really need linting to be working in Platform 7 and as I know old linting plugins (version <= 5.3) are not working here either.

Many thanks

Hi,

A fix for this bug will be released with 5.6.0: Validation of C7 diagram fails with `Error: showLintError is not a registered action` · Issue #3329 · camunda/camunda-modeler · GitHub
