Filter table if dates range is overlapping other dates range in another table

Greetings.

I have a Table 'C' what contains two columns 'colStart' and 'colEnd'. It's a Date Range.

What I need is a slider that allows to select a dates range and filter 'C' table showing only those rows that have any kind of overlapping with it.

To create the slider I just created a table using CALENDAR:

Calendar = CALENDAR(FIRSTDATE(C[colStart])|LASTDATE(C[colEnd]))

Thanks to https://community.powerbi.com/t5/Desktop/Calculate-days-from-filter-overlapping-date-ranges/td-p/216857 I already have a Measure that identifies that, but I can't filter the table using it:

Measure:

in_range = 
var startD = FIRSTDATE(ALLSELECTED('CALENDAR'[Date]))
var endD = LASTDATE(ALLSELECTED('CALENDAR'[Date]))
var finiv = MAX(C[colStart])
var ffinv = MAX(C[colEnd])
return
(finiv >= startD && finiv <= endD) ||
(ffinv >= startD && ffinv <= endD) ||
(finiv < startD && ffinv > endD)

Measure result:

I want to filter 'C' table, showing only where in_range is True. This is because I have related tables with 'C' that also need be filtered.

Hope you can help me. Tell me if you don't understand something. I have a test .pbix file but i don't know if it's possible to upload here.

Thanks!
