Method call with parameters in conditions using decision table

Issue

In the condition column of the excel decision true, i am trying to call a function, not a bean property, which take takes a parameter.

I am running into the following error:

[10,35]: [ERR 101] Line 10:35 no viable alternative at input '"language"' in rule "Agent Skills Rule_12" in pattern TaskSkillInfo
[10,47]: [ERR 102] Line 10:47 mismatched input '==' expecting ')' in rule "Agent Skills Rule_12" in pattern TaskSkillInfo

My condition is as follows:

task:TaskSkillInfo(getSkillValue("Language")=="e")

Is there a specific syntax that needs to be specified when using function calls in the condition column?

Here is the desired condition in DRL:

global AssigneeList resTO;
#From row number: 12
rule "Agent Skills Rule_12"
   
    when
        task:TaskSkillInfo(getSkillValue("Language")=="e")
    then
        resTO.add("test");
end
