I think you can try the following method to install this plugin via brat. I quote this instruction from the plugin’s github website:
Install the BRAT plugin via the Obsidian Plugin Browser and then add the beta repository “nothingislost/obsidian-embedded-query-control”
-
press this button in the BART plugin setting pane
-
paste the plugin name and press add plugin
-
Let BRAT do the rest work.
If the plugin is installed successfully, you will see the configuration option of obsidian-query-control in the setting menu.
