@Tim Hugall
Thanks for your time and patience, I was able to the feedback with the team but did not hear any updates till yesterday. Today I came to know that:
Global Secure Access Client on ARM64 is not yet supported. However, it is on the roadmap, but no timelines have been committed by the development team on this.
I will file a doc update request so that others in community having same query could be helped as well.
Please "Accept the answer", "Upvote" if your query has been answered. This will help us and others in the community as well.
Thanks, Akshay Kaushik
