Extract values from records

[Mikeman]

Hi,
I have product names with sizes inside, I would like to extract just the sizes, example :
Converse Black - size : 40
Adidas Amerocaban - size : 44.5
Nike black T-shirt - size : XL

Extraction in the column just to the right:
40
44.5
XL

In summary, this would be the value extraction just behind “:”
Do you have a solution?

Thank you in advance and have a nice day,
