Show Custom Fields of Taxonomy A in Taxonomy B Call when relational

[tolay07-dev]

Hey Guys!

Im in a dead end - following situation:

I have Cities and Bars as Taxonomy, and the Bars are linked to a city through a relational field.
the rest api call of the cities shows the relating bars, but not the gallery image nor the lat,long from google maps

Example Request where it shows the bars but not the image nor the coordinates (only of the city):
https://liquidmarket.wien/wp-json/wp/v2/stadte/65349

Request of the same bar:
https://liquidmarket.wien/wp-json/wp/v2/bars/61805

how can I add

"lat": 48.2829147, "lng": 16.380699, "Gallerie": "https:\/\/liquidmarket.wien\/wp-content\/uploads\/2021\/05\/logo-malfy-gin.png",
to cities taxonomy?

Appreciate your help a lot!!
