Shinyproxy 3.0.0 template Bootstrap upgrade to 5.2

Hello,
in Shinyproxy 2.6.1. I have written my own template for Shinyproxy using Bootstrap 5.2. (by replacing the Bootstrap 3.4.1 link tags in HTML head). After rewriting my template for Shinyproxy 3.0.0 using the new templates it seems that I am unable to use Bootstrap 5.2 without breaking Shinyproxy functionality (navbar disappearing, navbar buttons not working, apps not launching from index).

Is there any way to include Bootstrap 5.2 (both css and js) in the template without breaking it?

Thanks,
Filip
