How to use QMetry JQL functions in JIRA Software Filters?

[sm.arias]

I need to create a filter in Jira Software that allows me to bring the list of test cases created in Qmetry associated with issues: HU, Task, Sub-Task, etc ... in Jira Software

Etsoy using JQL in Jira Software filters like this:

issueKey in getStoriesLinkedWithTestCasesLike ("fixVersion = V_1")

but error is generated:

Unable to find JQL function 'getStoriesLinkedWithTestCasesLike (fixVersion = V_1)'.

which are recommended on this QMetry page:

https://qmetrysupport.atlassian.net/wiki/spaces/QTMJS250/pages/610107872/JQL+Functions

What should I do to activate these functions in JiraSoftware where I have a paid QMetry license as well?
