Ideas to show an Information Bubble in a modern page

Hi everyone,

I am in the process of putting together a new SharePoint Online site to replace Confluence in our organization, one thing I have not been able to find a viable web part for is an Information Bubble such as that shown in the screenshot below

Does anyone know of a way or an addon that will achieve this in SharePoint Online? We use this quote a bit in our Atlassian Confluence instance for Information, Notes, Warnings ect so I'm keen to find a way to do the same thing in SPO

Thank you in advance for any ideas/insight
