Remove a selected item from selectedTags Option once clicked or selected

Hello, everyone!!!
Please help!!! Tried everything but all failed.
What I wanted to do is to remove a selected item from selectedTag options. Below are my codes:

let selectionTagsOptions = $w ( “#selectionTags2” ). options ;

selectionTagsOptions [ 0 ]. label = $w ( “#selectionTags2” ). value ; // “First Label”
selectionTagsOptions [ 0 ]. value = $w ( “#selectionTags2” ). value ; // “first_value”

let opts1 = $w ( “#selectionTags2” ). options ;
opts1 . push ({ “label” : selectionTagsOptions [ 0 ]. label , “value” : selectionTagsOptions [ 0 ]. value });
$w ( “#selectionTags2” ). options = opts1 ;

Please see the highlighted push, 3rd line from the last. Tried it, also the shift, unshift and pop but it either removes the first option or the last option and not the clicked option.

I think the best solution is the splice, though I don’t know how to get the array of the clicked item in the selection Tag.

Thanks in advance.
