Postgresql query/admin GUI on Repl ? template, web or python?

I would like to have an online GUI for querying (and making small admin tasks) a Postgres database from

I can’t find any template or python app to do that.
Please note that i have tried to install pgAdmin but I can’t make it work on Repl. Maybe it’s the good solution if someone can show me

Can someone help me finding such a tool I could install on Repl ? either a web site i could install or best a python app
