ImportError: cannot import name 'OutputFile' from 'elyra.pipeline.component

[SkanderBahrini]

Hello,
I am currently using Elyra 3.15.0 for a Kubeflow pipeline.
I am trying to display images as output artifacts in the run output section.
I tried to import those packages
from elyra import pipeline
from elyra.pipeline import Pipeline
from elyra.pipeline.component import Component
from elyra.pipeline.component import OutputFile, OutputHTML, OutputText

Nevertheless, when running the pipeline it crashed and in the log, I got the following error
ImportError: cannot import name 'OutputFile' from 'elyra.pipeline.component

Thank you !
Looking forward for your answer
