Solution:
To prefilter the view with multiple terms belongs to one taxonomy and also offer the taxonomy frontend filter to users in that case you can use the view's filter hook "wpv_filter_query" to filter the views results based on terms given as prefilter to filter the view results as well as offer another taxonomy to filter results using frontend taxonomy filer on frontend.
The issue here is that the user's map block is not rendering.
Solution:
In this user's case the problem was that Divi was enqueuing its own Google maps scripts which was causing a conflict with the Toolset Maps import of the same scripts.
Disabling Google maps on divi resolved the Issue. This was done by going to the Divi theme options and locating the Google maps enable/disable toggle.
