Installing the sidebar-card

Hello, I am still a beginner in HA.
I installed the sidebar-card in the HACS interface but then it does not appear in the cards that I can add

in the Github it says to install lines in the ui-lovelace.yaml file but I can’t find this file.

Since ui-lovelace.yaml does not exist for me, i modify the configuration.yaml file by adding:

url: /hacsfiles/sidebar-card/sidebar-card.js
  type: module

but, when I check the pre-boot configuration, it tells me that:

Integration error: resources - Integration 'resources' not found.

however I confirm that the sidebar-card.js file is in the path

config/www/community/sidebar-card/

Help me please

If you’re not using YAML for your dashboard you add resources in the UI, under Settings → Dashboards → the three dots in the top right → Resources.
