New connectors are not seen in 1.6 UI

[brown3007]

Hi all,

I'm trying to build new connectors for custom pipeline services.
I use instructions from here
When I do it in 1.5, everything is OK, I can create new connections through UI, see their custom logos etc.
But when I try to do in in 1.6, I can see no new connectors in UI menu.
By the way, I can create these new services from API, though they have default logo (gear image).
I tried generating typescript types:
yarn run json2ts is not working from #18900
I got paths for new and updated files from openmetadata-spec/src/main/resources/json/schema/ and ran sh json2ts.sh <path> for each file.
Could you help me, what could I miss to do or do wrong?
Thank you!
