[um_show_content] shortcode not working

Hi,
I have the need to display, on same page, content depending on member accessing it, so that ‘Admin’ will see whole content, ‘User’ will see only its own one.
I have used the [um_show_content] shortcode for the purpose but it does not work at all, content is NOT displayed neither.
I have set it as [um_show_content roles=’member’] or [um_show_content roles=”member”] but nothing’s worked.
I have WP 5.6.2, UM 2.3.1 and using Elementor as page builder.
I have tried shortcode on both Elementor and default WP content editor with same no results…

Do you have some hints so that I can achieve my need? I would like to use this plugin for my customer’s members area pages, but if this content restriction cannot be achieved then I’ll have to switch to something else.

Thank you
