[12rambau]

What is the name of your repository ?
https://github.com/sepal-contrib/sepal-geemap

The name of your dashboard app
geemap

A short description of the app
Provide access to the power of geemap as a SEPAL application

Is your module requiring a GEE account ?
yes

Any comment you want to add
We should use the logo of the application itself instead of the SEPAL one. You can find it here: https://geemap.org/assets/logo.png Note that not all the functionalities will be available even if they are displayed as they interact with the underlying notebook. I'll take issues one by one if people complian but that's good enough as a start

Support for geemap will need to deal with how geemap initializes connection to GEE. See https://github.com/openforis/sepal/issues/286 and https://github.com/gee-community/geemap/issues/1558.
