I am developing an Outlook Web Addi for Web Outlook 365. The title of my addin is bigger and it is being truncated in the addin pane. Currently there seems to be no API support in office.js to edit the styling of the title in Outlook Web Addin. Is there a way that can achieve this?
I have raised the same question at the Stackoverflow also: https://stackoverflow.com/questions/60070639/outlook-web-addin-issues
