Safari touchbar fillups

Hi!
I love how BetterTouchTool changed the way I use my MacBook but I'm still working on the configuration that fits me best.
I'd like to set up the Touch Bar to show the fill-up forms suggestions as well as my own control strip on the right.
I've tried the App Specific option "show app default Touch Bar ** hide control strip in case BTT is activated" hoping it will fix my problem but with no success.
Maybe I misunderstand the way it should work but it would be great to have the access to BTT buttons as well as some good apple shortcuts that I can't configure by myself.
Thanks!
