Problem:

The problem here is that the user wanted to add a spinner graphic to their custom search that was built using Blocks.

Solution:

Unfortunately it is not possible with the block editor to add a loading spinner, however if you created your view with the classic editor you will be able to add a spinner or loading graphic.

Since you are using our Toolset blocks you can enable the classic editor by going to Toolset -> Settings -> Editing Experience and enable "Show both the legacy and Blocks interface and let me choose which to use for each item I build"

This should allow you to go to Toolset -> Views and from there you can create your view.
